The Dunham Group

At The Dunham Group, we never lose sight of the fact that our in-depth commercial real estate knowledge and market specialization can help shape our communities. That’s why we are a commercial real estate brokerage company with values. Located in Portland, Maine, our firm adheres to the highest ethical standards to provide honest, insightful market analysis for results-oriented brokerage and consulting. This is how our team of commerical brokers have developed loyal, long-term relationships with our clients for decades. We build up portfolios with our collaborative and data-driven approach, but more importantly we build up partnerships. Whether you are an individual investor, a small business owner, or the CEO of a large corporation, you are a respected and valued client, and The Dunham Group will help you attain your commercial real estate objectives.

Putting clients first has been the focus of our work at The Dunham Group for over 45 years. Founded by Tom Dunham in 1976, our firm’s reputation was built on Dunham’s strong ethical foundation, hard work, and feet-on-the-street approach. Through the years, we have been committed to the education and retention of the best professionals, where passing on industry wisdom and values from one generation of brokers to the next happens organically. This has enabled us to grow into a team of eleven exceptional brokers, with Justin Lamontagne named as Designated Broker in 2019. 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.
