The Dunham Group

Justin is recognized as one of the leading experts on industrial real estate in Maine. With over a decade of experience, he has successfully brokered transactions in all sectors, specializing in industrial, office, and investment properties. From strategic planning and representation for both buyers and sellers, to site searches and commercial property valuations, his exceptional market knowledge and expertise is an asset for clients looking for not only results, but a lasting relationship. Carrying his Rotarian principles forward in every deal, Justin is always looking out for his clients’ best interest and often talks people out of deals rather than into them. As such, he has fostered a reputation for being a genuine and trustworthy partner for clients.

As someone who approaches the market with a broad lens to understand all the different angles, positions, and perspectives, Justin is someone both clients and colleagues look to for his market insight. In 2013, Justin was named the Maine Commercial Association Realtor of the Year. In 2015 he earned the prestigious CCIM accreditation, an international membership comprised of the world’s top commercial real estate professionals. In 2017 he earned the Society of Industrial & Office Realtor’s (SIOR) designation, a global network of only 3,600 industry leaders. In doing so, he became the 5th broker in the state of Maine to carry both CCIM & SIOR honors. Annually, Justin is the author of The Dunham Group’s Greater Portland Industrial Market Survey, a comprehensive study and inventory of the local industrial market.

“I enjoy helping business owners shape the success of their company through real estate. A brick-and-mortar location impacts that success and if I can lend my expertise to help a business grow and create more jobs, it’s very satisfying.” - Justin

Justin is active in several Greater Portland philanthropic and professional organizations. He currently serves on the Board of Directors of the Maine Commercial Association of Realtors (Past President), Maine Cancer Foundation (Vice-President), Town & Country Federal Credit Union, and Portland Little League. Justin is also an active member of the Rotary Club of Portland, the Maine Real Estate Development Association, the Portland Chamber of Commerce, and the CCIM & SIOR New England chapters.

Justin joined The Dunham Group in 2011. In 2016 he earned Partnership in the firm and, in 2019, was named Designated Broker. He has worked in commercial real estate since 2006 and has a degree from the University of Rochester (BA ’02) and an advanced degree from Boston University (MS ’04). In his free time, Justin is an avid water skier, snow skier, hiker, rock climber and plays organized softball.

He lives in Portland with his wife, Marycelina, their children Katherine and William and their dog, Fenway. His wife is a 5-year breast cancer survivor, an experience that has contributed to Justin’s empathy for others, commitment to having a true work/life balance, and his focus on giving back.
