Put Our Collaborative Approach to Work For You
For over 45 years, The Dunham Group has provided in-depth market knowledge and trustworthy representation to our clients. Our objective is to help our clients realize their vision and this commitment has helped us build long-term, loyal partnerships. We like to get to know our clients the way we know Maine’s commercial market properties – which means we listen, we pay attention, and we do our research. With our insightful data analysis, local expertise, and collaborative approach we connect our clients with the right opportunities for their growth.
On working with Justin: “Once we got there and saw the space, he had done his research. He had tons of data and facts. I was blown away. Immediately we could have a pretty informed decision that this was worth pursuing or not.”
— Tom Ruff, Orange Bike Brewing Company
