Quality, Value, Service

John was tremendous in helping us with a very complicated project involving planning, designing, permitting, and collaboration with multiple private and public entities. Throughout the process, John was professional and effective, and we realized the outcome we had desired!

Ron ChenailHomeowner - Adams, MA

John Dupras and Greg Vigna were very professional and extremely helpful in guiding us all the way through the process of gaining a permit to expand our home near a protected wetlands area. We had been unaware of this designation on our property and of the potential restrictions. Trinity Engineering had the required experience and knowledge to advise us about the limitations and to manage what could have been a difficult process.

Thank you Trinity Engineering for making this happen.

James ByrneHomeowner - Williamstown, MA

I have been in the construction business for over 35 years and have hired many engineers. I found Trinity in 2008 when I began the renovation of The Hermitage Inn and have never used another company since. He is professional, responsive, and a pleasure to work with - I wouldn't use anyone else!
