What our clients say about us.

Managed Computer Services came through for us during a vulnerable period when our organization experienced a sudden loss of our IT manager and we were left with a potential disaster and no direction for our IT future. MCS was able to come in and quickly assess our immediate needs and put in place policies, procedures, software and equipment that saw us through this potential disaster and put us on the correct future course in the interim.

Thank you, the new computer David built is running well. Lots of room and I have found all my contacts. I have cleaned up a lot of stuff. Thank you again. You’re the best! I wish I had more business to send your way. However, if a problem arises I will call you first.

Thanks for your professional opinions! I truly value them. With all the scams that are going around these days, you have NO idea who to trust. People are even impersonating the IRS –what’s next.

Hi! This is Marilyn and I just wanted to let David know that I can’t express my appreciation for all the hard work he did to recover my photos. I really appreciate the extra effort you all took to do that for me. Thank you very much. I would highly recommend you.
