“I have been personally involved with the computer field for over 15 years and have known OSit for the last 5 of these. With the introduction to our practice of the Orthotrac system. Dennis and his company OSit are the most reliable & professional company that I have dealt with in that time and I can unconditionally recommend them to you for your computer needs”

Many thanks for your combined efforts in setting up our computer system. Operating two businesses and having one daughter at university and two daughters at high school, I have great "peace of mind" knowing that you are only a phone call away should any problems arise.

We are a small business who have been using Osit for a couple of months and in that time we have found them to be extremely professional, trustworthy, honest and fair and can’t recommend them highly enough.  One of their outstanding features we feel is their follow up calls to make sure what they have supplied and provided for us is what we needed.
