Louise Pockoski

Treasurer, Miyoshi America

We have been using Whittlesey Technology as our service provider since the mid-2000s. They have easily managed multiple server and software implementations over the years while giving us the communication and proactive guidance we need. They have also provided very responsive day-to-day support. We look at Whittlesey as a trusted partner and part of our team.

As a health care provider, we need responsive, secure, and fast technology. Whittlesey Technology makes that happen with ease and great communication. We highly recommend them to any business that relies on technology like we do.

Kim Kegley

Practice Manager, Connecticut Oncology Group

We appreciate the open communication and willingness to anticipate issues and plan accordingly that we get from the Whittlesey team, as opposed to a narrowly retroactive, 'forensic' approach.
