Thomas N. O’Brien

Through his professional career, public service tenure and personal civic involvement, Thomas O’Brien has become innately familiar with the market forces, community needs and politics that drive planning and development in the Boston region. At HYM, he has put that depth of knowledge to work, leading the successful development of some of the area’s most notable real estate projects, including Boston Landing, Northpoint, Bulfinch Crossing and Suffolk Downs.

As the Founding Partner and Managing Director of HYM, Mr. O’Brien has intentionally built a company representative of Boston’s diversity, drawing talented individuals with multidisciplinary backgrounds to bring new perspectives to commercial real estate development.

Mr. O’Brien previously served as a Managing Partner for JPI, a national owner of multifamily communities, and as a Managing Director in Boston and New York for Tishman Speyer, one of the world’s leading real estate firms. O’Brien also led the Boston Redevelopment Authority as its Director and Chief of Staff, overseeing the development of over 12 million square feet of projects in Boston, from 1993 to 1999.

As an advocate for Boston and its people, Mr. O’Brien helped advance fair immigration policies as a Co-Chair of the Massachusetts Business Immigration Coalition, including joining the coalition that successfully enacted the new driver's license provision for people who are not yet documented. Today, Mr. O'Brien continues to support numerous social organizations that aim to give Boston’s youngest residents more opportunities for success.

With his wife Patricia, he is a parent to five children and lives in Boston, MA.
