Why Computer PRO
A local team that has been fixing computers in St. Charles for 30 years
Computer PRO Unltd. was founded in St. Charles in 1996 by Paul and Sharon Wheeler. Sharon still owns the company, and Josh Giesing runs it day to day as President. You deal with the same people every time. The tech you talk to on the phone is the one working on your computer or your network.
We fix desktops, laptops, servers and networks for homes and businesses across St. Charles County and the St. Louis area, including St. Peters, O'Fallon, Wentzville and Florissant. A lot of what we fix never has to come to the shop. If a problem can be handled remotely, we do it that way and save you the drive, whether you are down the road or in another state.
Family owned. Woman owned. Locally run since 1996.
You talk to a tech
No call center and no script. When you call, you get someone who can actually look at the problem.
We explain the fix
When the repair is done, a tech calls and walks you through what was wrong and what we did, so you can ask questions.
Remote first
Many repairs happen over a secure remote session, so you don't have to unplug anything or bring it in.
One team for it all
Business phone service, Microsoft 365 email and cloud backup from the same people who fix your computers.
