We have been associated with Computer St. Louis for many years and use their services for all our computer needs.

Dave Breen

V.P. & C.F.O.

Computer St. Louis is our preferred partner - providing timely professional service and support. We have been partners with Computer St. Louis for almost 10 years, they understand our needs and go above and beyond to provide service. They have helped us streamline our VOIP and Data service and consolidate our data center needs.

David S. Smith

Director of IT

We transitioned to Computer St. Louis in October 2015 after our IT staff resigned with minimal notice and maximum responsibility. Computer St. Louis inherited a mess which had critical issues in need of immediate resolution as well as long term planning. They divided their resources accordingly to ensure both of these happened. Computer St. Louis created stability in our network which created confidence for our staff and immediate increases in production. Computer St. Louis has worked with us over the last 8 months to decrease our server footprint and increase our network efficiency. Their staff is responsive and works to solve a problem not just simply fix an issue.

Shawn Farris

CFO

We have been working with Computer St. Louis for several years. Their staff is professional, courteous and knowledgeable. They are able to respond and resolve any issues that we may have on a timely basis. One year we upgraded our server, workstation and operating system - and even though we had to work until Midnight on Friday night to minimize downtime, the job got done and it was fun. I would recommend them to anyone.

I have been using Computer St Louis for nearly 15 years for our business. The team at Computer St. Louis can't be beat! They are always competitive on their prices and their service is the best in town. Very helpful recommendations when trying to find that 'perfect fit' solution. They have constructed many specialized PC's and Server for our office and they have always performed exactly as advertised. There is nothing better than having a great “English Speaking” support technician to assist you when you have a frustrating issue at hand. Computer St Louis has the answers that I've needed, on time, every time.

Hi Seth, Just wanted to pass a comment Dr. G sent me regarding Brandon, “I showed Brandon that I was having a problem with my laptop. Long story short, we arranged a home visit and he was FANTASTIC!”. This level of service to our senior partners is really helpful in demonstrating the quality support CSTL has been providing us. 

Dr. D

Muhamed was very professional, enjoyable to be around, and knows his stuff. I am very thankful that you sent him out to help with my new computer. It is always a good thing when you have a tech that can fix issues on the first attempt and not make several return trips. You guys are very lucky to have him on your team. THANK YOU MUHAMED FOR YOUR HELP!!

Todd M.

Andrew, I cannot thank you enough for the time you spent with us today addressing our tech issues.  You are amazing!  I appreciated your expertise, problem-solving skills, and how you took each issue so seriously.  You definitely left us in better shape.

CSTL is lucky to have such a capable IT-man, in Andrew.
 Thank you, Andrew, for your quick and efficient solution to what had been an ongoing problem. 
If it were up to me, I'd give you the rest of the day off.

I think the ticket for Email/Outlook issues is officially closed and we are all in good working order now. I wanted to thank you, Allen, Rico and anyone else that had time on this ticket. We appreciate that the team stayed on top of this and worked hard to get us back up as quickly as possible. Thank you again!
