We appreciate Tom for his responsiveness to all our IT needs. His work for us allows us to do our work. We appreciate, as well, his recommendations of products and solutions he believes would fit well with our business. He is a great resource!

Laura Eads

Operating Partner - Kiddie Academy, St. Louis

Arch Technologies has been working with MCS for over 7 years. They helped with a number of iterations of hardware and software integrations for us over the years, and most recently has put into place a comprehensive IT security system. Tom is highly knowledgeable and responsive to our needs and I would not hesitate to recommend him to any business that wants to outsource their IT solutions.

I’ve been working with Tom at Arch Technologies for as long as I can remember. They are always responsive and dependable, and the price is always reasonable. They’re fantastic.

Seth Reeder

Probably the best hidden gem of an IT company in St. Louis. They respond quickly, are reasonably priced and make sure we are prepared for the future, not just solving issues we have today. We highly recommend their services for any small businesses that need a better solution.
