Tandem Computer Services started as a part time venture in response to the increasing requests from friends and neighbours to “fix my computer”.  After a career with Compaq and HP, I have been lucky enough to be able to pursue Tandem as full time venture. We started Tandem with one ideal: Provide quality products and service at a fair price. Period. Over the last 18 years we have proven our dedication to this simple philosophy. We cater to residential and business clients in the Dundas/Stormont region of Eastern Ontario.
