Advanced Cybersecurity & IT Support From A Trusted Family Owned Business
At Computerease, we understand how important trust, consistency, and a personal touch are in choosing an IT partner—because we’ve built our business that way from day one.

Whether you’re an office manager looking for reliable support or an IT director needing a trustworthy co-managed partner, our commitment to integrity, transparency, and long-term relationships is built for you.
“You deserve an IT partner who’s fast, dependable, and

St. Louis TagDan was incredibly kind, patient, and helpful — hands down the easiest laptop transition I’ve had in over 20 years! I was able to work all day while he handled everything, and he also got our conference room tech running smoothly. Everything feels easier and better than our old setup — the Computerease team is really good.
