What Clients are Saying About Absolute Computer Systems’ Services

Are you searching for an IT services company? Are you wondering how satisfied you’ll be with their services? There’s one sure way to know, and that’s to read reviews supplied by small business owners like you. Here’s what some of our clients think about our IT services.

Right here for us – we could not ask for better.

I do not often write these but.

I wanted to share a recent experience we had with our IT service company (Absolute Computer Systems (ACS)) that illustrates their flippin amazing level of service and expertise.

On one of our busiest days of the year, our internet went out at the salon, and I was at a loss for how we would be able to take payments, make or receive phone calls, send confirmation emails, etc., and just keep our doors open!

That’s when Tom Tassi and his ACS team stepped in and literally saved the day. They were in our salon in less than 60 minutes (trust me, at that point, minutes mattered!); they were able to re-configure our credit card terminals to be wireless and supplied a cell phone hotspot for us to use to continue taking payments. They also set up our employees’ cell phones to accept the calls coming into the salon, allowing us to continue serving our customers without interruption.

I can’t stress enough how much ACS helped us during this difficult time. Their quick thinking and technical expertise truly saved the day and kept our business running as smoothly as possible. Not only were they able to appreciate the urgency of the problem (me all but screaming into the phone might have helped with that), they also stepped up and int ot he mess with us and provided a solution that was above and beyond our hopes (let alone expectations). I do not doubt that ACS would do the same for any salon owner needing support.

I am just saying that having a reliable and competent technical support team is more important than ever. Absolute Computer Systems has proven to be exactly that for our salon, and I have no hesitation in recommending them to other salon (and, of course, other business) owners.

If you are in a similar situation, don’t hesitate to contact Tom Tassi and his team at Absolute Computer Systems 1-262-942-8572 or for assistance. I’m more than confident they will go above and beyond to help get and keep your business running smoothly.

We would (and have and do!) definitely recommend their services

Absolute Computer Systems is the first IT company we have used that promptly responds to our needs. They always take our calls and get back to us with help as soon as possible. We would (and have and do!) definitely recommend their services.

Martin Brand – President at Martin G Brand Ltd

Quite simply – they are the best organization I have ever dealt with for ANY service.

I’ve used ACS as my law firm’s IT source for several years. Simply put – this is the hands-down best organization I have ever dealt with for ANY service. They respond quickly to my calls and work tirelessly to fix any computer or related issues my firm has. It must be a great place to work because I’ve been dealing with the same techs for all the years I’ve worked with them. They even make house calls!!! Who does that these days? I SUPER recommend Absolute Computer Systems for all your computer and IT needs.

Vital to the operation of my business.”

Absolute Computer Systems is the very best IT service provider my firm has ever used. It would be a significant understatement to say they go to great lengths to provide excellent service. In addition, they are often in front of the cutting-edge regarding IT Security. The company is vital to the operation of my business and very much appreciated by me personally.

Howard Goberstein – President at NorthShore Professional Group

I highly recommend Absolute Computer Systems.

Absolute Computer Systems has looked after my small business and personal computers for over ten years. I can call with a problem; someone is dialed in remotely, usually while I am still on the call. If they can’t fix it remotely, they are in my office within an hour to diagnose the issue, and I am back up and running with minimal downtime. The staff is friendly, responsive, and knowledgeable. I highly recommend Absolute Computer Systems.

Judy Busche – President at Judy Busche LLC

Years of awesome service!!!

Tom and his team go above and beyond every time. As a business owner, if my computers are down, so is my business. Tom is always right there to save my life. This week, Jeremy took over my computer remotely, and within 15 minutes, he corrected my problems and allowed my business to keep moving; Kudos to Jeremy, Don, and all. These guys/gals are the best. Years of awesome service!!! THANK YOU! Sue, INNOVATIVE FLOORS

Sue Radder – President at Innovative Floors

I highly recommend them! (Veteran owned too!)

Our two companies have worked with Tom at Absolute Computer Systems for over 12 years, and the honest, stellar service he and his entire office perform is above average in the industry. He has saved us from many catastrophes and turned them into a pleasant sigh of relief. I highly recommend them! (Veteran owned too!)

Cindy Nicoletti – Owner at Celebrate Our Town

Special thanks to Tom and his staff for always being there when I need them

Tom Tassi and his staff are hands down the most experienced and helpful computer techs I’ve ever come across in all my years. I have traveled the USA and abroad and have never been treated so kindly and professionally as Absolute computer has done for me. So let’s get down to brass tacks; Tom and his staff let you know what’s wrong and what can be done, and you’re given a fair price on the spot to fix the issues. Special thanks to Tom and his staff for always being there when I need them and for sending helpful advice to my email about upcoming and ongoing threats to be aware of.

10/10 would highly recommend them!!!

I have had the pleasure of working with this company twice while I worked at two different places. And every time, everyone at Absolute Computer Systems has been nothing short of incredible to work with. They handle everything professionally and never leave a task unfinished; the whole team feels like a big family you adore! They are on top of an issue THAT day, and their pricing is fair! I recommend ACS to every company; they are top-of-the-line in the industry! We will never leave them. Tom, the president, ensures everything runs smoothly and always does! 10/10 would highly recommend them!!!

Sasha Stojic

I have recommended them to friends and family.

Very fast service at reasonable prices. Absolute “absolutely” cares about their customers. I have found them to be very helpful to small businesses and home offices. ACS will come in-house to check out a problem first. Then, if needed, they take the computer back to the shop for service with as little downtime for their customer as possible. I have recommended them to friends and family. Absolute Computer Systems is the best!

Darcelle Matus – Office Associate at Keno Collision & Service

If you are looking for fast, reliable, professional service, look no further than ACS!!

Excellent doesn’t begin to describe Tom and his crew at Absolute Computer Systems. My laptop went down in the middle of teaching in a virtual world, and Tom swooped in to rescue me! He was able to make sure that learning was not disrupted, and I was able to continue to provide my students with the instruction they needed. It was just a few days before I had a new laptop in my hand. If you are looking for fast, reliable, professional service, look no further than ACS!!

Jennifer Milligan

I highly recommend Absolute Computer Systems!!

I have known the owner Tom Tassi for many years now. What you want in a company like his that advises, protects, and services your Phones, Computers, and office equipment is reliability. Tom and his staff are and have always been quick to respond and come save the day. I highly recommend Absolute Computer Systems!!

Kelly Burris – Vice President of Sales at Integrity Payments

They regularly exceed my (admittedly small but, to me, really important) expectations.

Absolute Computer Systems has been my one and only go-to Computer Sales Service and Repair Shop for over a decade. Their exceptional service and expertise repeatedly earn my trust and confidence whenever I or someone from my shop calls for help. Whether it is quickly fixing user errors or managing my hardware, software, and phones ( AND COMCAST!), they are the best in the business. I highly endorse Absolute Computer Systems, and the people who work there ( Wade, Don, and Tom ) have never let us down. – Don Miller, owner of Mike More Miles in Waukegan, Illinois.”

Don Miller – Owner at Mike More Miles

“they take care of us very well.”

Absolute Computer Systems has helped greatly in getting our systems up to date and working great. They provide updates (before we know we need them). Whenever work needs to be and is done, it is always done right the first time, something we have not had before and really appreciate. They are very responsive and have always been there when we need them. – Dave Wucinski, Owner, Pinnacle Precision Technologies

Dave Wucinski – Owner at Pinnacle Precision Technologies

 “ACS brings value that exceeds their costs.”

Just a quick note to say thank you for your quick response to the issues we were experiencing with SharePoint. Your near-relentless attack on Microsoft (I also appreciated you including us on all emails so we knew where we were at all times) resulted in comparatively minimal downtime.

Your team is always Easily accessible and quick to respond. Additionally, we genuinely value your proactive analysis of our hardware and software with suggestions/solutions before issues surface.

In Short, the level of service you folks routinely provide is better than anything we have had before. As a result, you bring value that exceeds your costs.

Michael Schack – Principal at Dayton Street Partners

“The best of all worlds, customer service, quality of work, and cost.”

The Biggest / most significant benefit(s): Easily their Reliability. It is invaluable to our school district to have a partner we can count on to do quality work on time and within our budget.

Their Top-notch customer service is not something we have experienced in the past, and ACS has provided that and more every time.

If you could have the best of all worlds, customer service, quality of work, and cost, why wouldn’t you? We love and highly recommend Thomas Tassi and the ACS Team.

Charles Ongena – Director of Technology at Beach Park School District #3

They took the time and effort to learn our software.

Our needs are very specific and unique. The fact that the technicians at ACS have made themselves familiar with our software (and have their support number on speed dial) helps get any problems we might have solved wholly and quickly.

There is never a noticeable drop in capabilities among their technical personnel that I have experienced with past IT Service Providers.

We would very highly recommend them!

Barry S. Schiffman – from The Club at Strawberry Creek

Above and Beyond

Absolute Computer Systems goes above and beyond for the Hope Council on Alcohol & Other Drug Abuse, Inc., helping a small Kenosha nonprofit to operate at full capacity. We get quick service that is high quality at a reasonable cost.

Guida Brown – Director at Hope Council

Tom and his techs have been a godsend for me.

ACS has always been responsive to my backup needs and has helped me overcome several windows and hardware-related problems. I cannot use my hands, and Tom and his techs have been a godsend for me. Smart, courteous, and most helpful.

David Allard

I always recommend Absolute Computer Systems!

We have worked with Tom Tassi for years. The thing I admire the most is his dedication and honesty in all he does. He takes pride in his work. If you are looking for assistance with computers and anything related, he is your guy. I always recommend Absolute Computer Systems!

Tammy Kuntunen – Office Manager at Dr. Patrick Crawford DDS Office

Anything pertaining to my PC, I call Absolute Computer

I have depended on Absolute Computer Systems for quite a few years to keep my personal PC up and running. Ok, so it’s not a business PC or a mainframe, but to me, it is! The experts at ACS have always been available when I get a virus or set up a new PC and transfer from my old one. They have no problem coming to your house and servicing your PC rather than taking it in. Anything pertaining to my PC, I call Absolute Computer.

Sandra Crawford

A daily phone update on the progress if your computer is being repaired

Many reviews about Absolute Computer Systems seem to relate more to businesses. Still, Tom and his staff are also great at working with everyday folks with computer problems. Very responsive, including a daily phone update on progress if your computer is being repaired. ACS has helped me twice in the past few months, and I appreciate their service.

Barbara J.

Excellent and fast service. I would (and do)  highly recommend Absolute Computer Systems!

Adam Rodgers

I highly recommend Absolute Computer Systems for all of your computing needs!

Thomas and Absolute Computer Systems are awesome, five stars all the way! I fall somewhere between a tech wiz and a Luddite, so I know when I need to call in the experts, and that’s precisely what ACS is – a team of highly professional experts that know how to get the job done and do it right! Outstanding customer service and an absolute pleasure to work with. I felt that I was in capable and caring hands the whole time, thanks Thomas and ACS! And because of their remote capabilities, they can hook you up with whatever you need anytime, no matter where you are. I highly recommend Absolute Computer Systems for all of your computing needs!

Anthony Scaletta

I have recommended them to many friends and family, and all are still talking to me!

What can I say? The entire staff, starting with Tom, are just fantastic. They have solved every one of my PC issues, and I seem to have my share because I am PC challenged—most of the time, they do it remotely, saving me time and effort. I have recommended them to many friends and family, and all are still talking to me! Seriously, these are people you can trust with a very valuable tool for your home or office.

Joyce Erickson

ACS is the real deal

Friends referred me, and my experience was excellent as well…fast and professional technical assistance with issues resolved. I appreciated Tom taking the time to share the information, which assisted me in keeping my computer running optimally. If you need knowledgeable computer professionals, ACS is the real deal.


Very helpful and offer a variety of services. They have always been patient and kind to work through issues and deserve a bigger office space for the amount of work they do.

Samantha S.

Total life savers

Tom and his crew are amazing. My work laptop went down, and they picked it up and had me a new one with all my info transferred in a couple of hours. Total life savers and the upgraded laptop is awesome!

Mike Sebena at Sebena’s Automotive

One of the best-kept secrets in Kenosha

Absolute Computer Systems is one of the best-kept secrets in Kenosha. The service I received was as professional as it was thorough. I was so impressed with the results I decided to write this review. I usually don’t. It helps that they are local, but I’ve driven to much more distant locations, where I received less satisfactory results and charged much more for it. I cannot express my appreciation enough for their expertise.

Knight Rook

Not just preferred – ACS is our ONLY provider.

Very Responsive (quick) support / Courteous, professional, complete service, and no new problems when they leave – what more could we ask!!??

Knowing Tom and his team are no more than a quick phone call away is very reassuring. We have tried other services in the past, but now it is either ACS or no one.

If you are looking for this service – these are the people to call. They simply do a fantastic job.

Maria Fliess at Retirement Advocates

Our on-the-spot, go-to IT ‘Team.’

Absolute Computer Systems has been our hardware ‘go-to’ team for almost ten years. Tom, the owner, is extremely ‘hands-on.’ His staff is helpful and attentive to any problem that arises. Computer issues, as we all know, crop up at the least convenient time, and the ACS team is here for us every time!

ACS keeps our computer system running smoothly and minimizes any downtime that occurs. They were there to get us up and running when a ComEd transformer blew and left us without power for several days. They coordinate with our software company to maintain hardware integrity and make sure it integrates properly with the software. They monitor, repair and maintain the very costly equipment that is the lifeblood of our business.

By allowing ACS to take care of our computer needs, we can keep our focus on building our own business where it should be.

Ann Urkov, JD – Office Manager/Energy Consultant at Lower Electric, LLC

Excellent & complete service

Your service is always professional, complete, and very much appreciated.

Ira Holtzman – CEO / Energy Consultant at Lower Electric, LLC

Immediate professional support

I worked with Tom and Absolute Computer Systems for five years at the Racine Community Foundation; however the Absolute Computer Systems is servicing all computer needs at the Racine Community Foundation for many years. Tom is very knowledge, honest, professional and reliable, he responds to client needs within 0 – 30 minutes and sends the ACS’ staff immediately to resolve the problem. His services are high quality. He treats his clients with high respect and always is able to find resolution. Client satisfaction is number one priority for the Absolute Computer Systems. I would recommend the Absolute Computer Systems to all who needs fast and high quality computer service.

Edyta Odorowska-Duleba – Operations Finance Supervisor at AbbVie

I truly appreciated the peace of mind.

I have used ACS for years. I have had them for all of my business computer and networking needs. We had a dual hard drive failure about two years ago, and our backups were corrupted. Tom and his team were able to save and restore our primary customer and financial databases, saving us thousands of dollars and possibly our business. They have always been there for whatever the need has been. They are my first call if I am ever in need of anything they might carry or service. I can’t thank them enough for the peace of mind they give my wife and me for everything they do for us and our business. They keep us up-to-date and moving forward. I would highly recommend them to anyone looking for exceptional service. Thank you, Tom and ACS!

Bruce Marcquenski – Owner at Kenosha Turf Equipment | Snap Fitness Kenosha

Get Off of the Fence!!

I’m a long-term customer of ACS Kenosha, and there’s a reason. The words “excellent” and “impeccable” don’t do justice to the professionalism, service, or quality you get when working with the ACS support and sales team. Because they keep our computer systems in top order, our productivity is at an all-time high, and our computer downtime is nonexistent.

Whether it’s the little quirky things that cause slow start-up or more significant problems, like the blue screen of death, these folks know what they are doing and get things up and running — fast! And if you’re a business owner like me, downtime is costly! This is why we’re lucky to have ACS on our site keeping every part of our network and computer systems running smoothly as silk.

If you’re on the fence about whether you need to hire them or not, get off! ACS will be one of the best investments your money can buy and will help extend the lifetime of your computing equipment. Call them — now!

Kristine Evenson – CEO / President at CaptureHits Marketing Group

An around Awesome team

Kenosha Animal Hospital has been using ACS for a couple of years now. When we decided to go paperless about two years ago, we knew we needed computer specialists’ help. This was such a stressful time for us, as you can imagine. We knew we had made the right decision when Tom Tassi and his excellent ACS team arrived. The ACS team of experts was instrumental in helping us get everything we needed up and running to make this transition as smooth as possible. Plus, they made us laugh and were a fun group to have around, helping us to diffuse the anxiety due to all the changes. They are always there when we need them, and we understand how important it is for us to have minimal downtime. Our entire business depends on our computer system, and Tom and his very professional and efficient team ensure we always receive the absolute best customer service. We highly recommend them to any business, large or small, needing true IT professionals. Thank you, ACS!

Becky Carlisle – Office Manager at Kenosha Animal Hospital

Speed and professionalism

We really appreciate the speed at which Absolute takes care of us. Like many companies, when our systems have issues (which, thanks to them, is very seldom), it can and often does have wide-spread results.

The Absolute team will be there to look out for your company the way you do. They will be an extended parts of your staff and will do whatever it takes to get you taken care of.

I very highly recommend them.

Laura Bothe – VP at Bothe Associates

10+ years and going strong

It was the best day for me when I found this Company in the phone book!

When I called and talked to the staff about our Company’s needs and weekly hours of operation, they were very optimistic about their group’s ability to support us.

We have had support with the following:

  • Hardware
  • found us support staff for our software issues
  • are usually able to be on-site or dial into the system and have us up and running within an hour time (depending on the system issue)
  • have always gotten the best pricing on the needed equipment

We have been with Absolute Computer Systems in Kenosha, Wi. for over ten years…

Sue Stevenson – Office Manager at The Newell Company

Excellent advisor

Tom knows everything there is to know about computers, listening to his recommendations he has saved me a lot of time, trouble and money! Thanks, Tom, you’re the best!

Susan Fitzgerald at Wild Horse Promotions

Highly recommend

Tom and his company have fixed our computers and an all-in-one printer. With multiple users and computers, Tom has given us the best services, both on-site and at his place of business. I have recommended him to my family, friends, and co-workers and will continue to recommend him.

Lucinda Whitefoot at Homestead Realty, Inc

Excellent service

Tom is a great guy to work with, always has the customer at the top of his mind, and I love his innovative solutions to some common issues; he is not afraid to get off the reservation!

Richard H. Crockett – Marketing “Madness” Manager at EZSolution

Best of the best!

Tom and his company bailed me out of a tough spot after a significant network crash. Super responsive and an excellent value, it is truly a pleasure to have had Tom help me, my family, and my business. Without Tom’s responsive and knowledgeable help, I don’t know what would have happened. Tom has my strongest possible endorsement and recommendation. If you’re considering an IT professional, Tom sets the standard; he and his company are belt and buckle, head and shoulders above the rest. Not only did I find an excellent professional, but I also found a friend for life too. He is personable, has high integrity, and is flat-out a GREAT person, technician, and friend. I will not hesitate to promote Tom and his business anywhere or anytime; he is that good!

Stephen (Pete) O’Connor – Owner at MasterMind Realtors

They Took The Time (on Thier Dime) To Learn Our Software

We are in a unique industry, and Absolute Computer Systems can and does fulfill all our IT needs. If we have ever had a problem that Absolute was unfamiliar with, they have taken the time and performed the necessary research to solve it.

Absolute Computer Systems understands our needs and works proactively with us to address them. Recently, Absolute called me and indicated we had an issue with the server, and they worked to address it. However, it would be nice if other providers called and stated a problem was occurring with something before the situation became large in scope.

Terry Helton, President

“A godsend to me as I run my small business”

ACS has been a godsend to me as I run my small business. Tom seldom makes fun of my lack of computer expertise and is always available to assist. In addition, all team at ACS have been professional, personable, and rather funny!

My Advice: “Start with ACS and if you’re not satisfied, move on.” Everyone that I’ve recommended has stayed!

Mary Domes at DogDom International

Best IT Service Provider I have ever worked with

I can honestly say that Absolute Computer Systems is the single best IT Service Provider I have ever worked with.

Their response times are excellent; the employees know what they are doing, pay attention to details, ask questions, AND listen.

Chuck Snowdy – General Manager at Jensen’s Plumbing and Heating

It is an Absolute pleasure it is to work with Tom Tassi and his team of IT professionals.

The fact that Absolute Computers is locally located is, for us, a significant advantage. (My former IT service providers were in Milwaukee. Their availability always took till the next day. They did not show up with a smile or pleasant attitude. On the other hand, the Absolute Computer Systems crew has an attitude and aptitude of exceptional quality.

Tom Tassi and his crew are truthful and upfront. My previous providers would come for a service call, and it was routine for them to tell me I needed to replace or update some piece of equipment, and the required investment always turned out to be more than they started with—this has NEVER been the case with ACS.

My Advice: Get off the fence and get the best! Absolute Computer Systems! I have never been disappointed in their work or the employees.

Dr. Pat Crawford D.D.S.

Personalized, Fast, and Professional Attention

I genuinely appreciate the personalized, fast, and professional attention we receive whenever we need help. Unlike other IT Service companies, we have worked with in the past when These folks say they are going to do something—they do it. (At or under budget!)

There are few people I have worked with as ready, willing, and able to help me keep my company running and working efficiently as I want it to – Tom Tassi and his Company – Absolute Computer Systems, are definitely on that list.
