Donald Brennan Owner & Real Estate Broker

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. I started our brokerage business after realizing that the efforts and investment we made in our development product weren’t being relayed correctly by the outside agents we were using to sell our developments. Employing my own agents solved this problem.”

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.

Sellers appreciate Brennan’s polished and professional marketing materials, extensive network, knowledgeable salespeople and successful pricing strategies. Buyers often come to Donald and his team already knowing of the quality housing Brennan develops, their in-depth knowledge of the neighborhoods and property types, and their ability to uncover untapped buying opportunities the average broker isn’t able to see.

“Our clients come to us looking for better service to fulfill their real estate needs. I am never satisfied with delivering a product or providing a service that meets with minimum expectations. I, and my salespeople, do not aim to be average. We do not follow the herd. The business opportunity to me is based on the belief that we can do better for our clients. And that our clients deserve better.”

When a client employs Brennan as their trusted adviser, they are getting not only an agent that is trustworthy, capable and successful, but a firm that backs up that agent with every possible resource, virtually guaranteeing delivery of the best deal possible.
