Testimonials

Quality, Value, Service

John was fantastic to work with! Very personable, responsive, reasonable and went out his way to help in any way he could to efficiently complete our complex project.

Audrey MatysLandowner - Clarksburg, MA

Over the last decade plus I have hired and interacted with Trinity Engineering many times both as a client and as a part of a local regulatory body. In all cases Mr. Dupras and staff have been professional and portrays a keen sense of current environmental laws and processes. From State wastewater systems/potable water suppy to variations in FEMA floodplain designations Trinity Engineering can assist with your engineering needs. A bonus provided by this company is an easily understandable explanation of project details and helpful guidance long after your individual project has been completed.
