Born and Raised in Maine

I was born in Dover-Foxcroft and grew up nearby in Dexter. After receiving my bachelor’s degree, I worked in multiple roles, including roles in public service as a policeman and a fireman to help my community.

Eventually, I wanted to utilize my knack for mechanical systems to help homeowners and property managers with all things related to heat pumps. During the past decade, I learned trade secrets and best practices in the HVAC industry. Then I started D&J Mechanical, LLC to install heat pumps throughout my community.

As a father, I am very family-oriented and support my children in developing their interests. At the same time, my children know that I work hard to deliver excellence for my clients. As a result, I encourage them to give their best in all that they do.

My clients receive high-quality installations and dependable service from a local business owner who is passionate about serving his community.
