For over twenty years, Donald Brennan has built a career founded on his expertise in architecture, experience as a New York City developer, and his in-depth understanding of the real estate landscape — bolstered by his dedication to the community, historic buildings, and the future of the city's neighborhoods.

During college, Donald would walk the Brooklyn neighborhoods of Brooklyn Heights, Cobble Hill, and Carroll Gardens, exploring and absorbing how the architecture and housing stock would change with the blocks. “I fell in love then with the low-density row houses of brownstone Brooklyn and have grown to love and appreciate them even more as I continue to live, work, raise a family and enjoy a walkable urban lifestyle.

It was then that he and his wife chose Brooklyn Heights to raise their family, and where to this day he is heavily invested in the community.

A former board member of the Dodge YMCA, Donald chaired the Strong Kids Campaign and was responsible for raising more than $300,000 during his tenure. Currently, a board member of the Brooklyn Heights Association, Donald serves on the executive committee and chairs its landmarks committee. He is an advisor to the Historic Districts Council of New York and teaches urban planning in New York City high schools.

My innate skills, combined with my formal education and experience as an architect, provide me with a unique and invaluable skill set to deal with both development and brokerage effectively and successfully. 

Brennan’s brokerage services initially focused on low-rise, brownstone Brooklyn neighborhoods primarily townhouses but it has expanded into the other boroughs and now covers all types of housing.
