Andrew Brennan is joining HNTB Corporation as its national transit and rail practice consultant and VP, focusing on advancing the growth of HNTB’s profile in the transit industry while providing strategic advice to the firm’s transit team and clients. He is based in Boston and serves as an expert technical resource for the firm’s clients nationwide.
Brennan served nearly three decades with the Massachusetts Bay Transportation Authority (MBTA), serving in several environmental leadership roles. Prior to joining HNTB, he served as MBTA’s sr. director, energy & environment, where he was responsible for the implementation, management, and coordination of the authority’s environmental policies, programs, and procedures.
While at MBTA, Brennan successfully managed and completed the Federal Transit Administration’s Capital Investment Grant/New Starts process for the Green Line Extension project, which resulted in a nearly $1 billion grant for half of the project’s capital costs.
Brennan also established MBTA’s first energy management program and led the procurement that resulted in sourcing 100% of the authority’s electricity from renewable sources, making it the largest transit agency in the U.S. to do so.
Earlier in his career, Brennan was chief of staff for the Massachusetts Executive Office of Environmental Affairs. In that role, he was responsible for the effective operation of the executive office through strategic planning and coordination of policy developments and management initiatives. He was directly responsible for the developing, coordinating and implementing an ongoing secretariat-wide communications strategy.
