Our Team

Putting clients first has been the focus of our work at The Dunham Group for over 45 years. Founded by Tom Dunham, our firm’s reputation was built on Dunham’s strong ethical foundation, hard work, and feet-on-the-street approach.

We focus on educating and retaining top professionals, ensuring the transfer of industry wisdom and values across generations. This commitment has grown our team to thirteen outstanding brokers, with Justin Lamontagne becoming Designated Broker in 2019.

Our Market Specialties

Unlike other commercial brokerage firms, our brokers focus on specific sectors — office, retail, industrial, multi-family, land, investment — and have become experts in their industries.

Our record of success demonstrates how The Dunham Group has been a leader in commercial real estate and a trusted partner for individuals and businesses in Maine.
