SOMERVILLE, Mass. — TransMedics Group, Inc. will establish its new global headquarters and manufacturing operations at Assembly Innovation Park after securing a 498,000-square-foot, full-building lease at the Somerville life sciences campus developed by BioMed Realty.
The move positions the organ transplant technology company in a newly constructed 12-story research and development facility designed to accommodate large-scale manufacturing and corporate operations. The building, which is LEED Platinum and WELL certified, was developed to support high-intensity life sciences use while emphasizing employee wellbeing and long-term operational flexibility.
The 16-year lease covers 100 percent of the building. In addition, TransMedics has acquired the adjacent land parcel and a portion of the campus parking structure to allow for future expansion as the company continues to scale its global operations.
“We selected our new headquarters to support the full scale and complexity of our mission,” said Waleed Hassanein, M.D., President and CEO of TransMedics. “Our innovation will accelerate and thrive in this world-class facility that BioMed Realty built. It provides the infrastructure, flexibility, and long-term growth capacity we need to support our teams and the broader transplant community as we continue to advance life-saving transplant technologies and scale our impact globally.”
BioMed Realty said the project reflects its long-standing focus on developing purpose-built infrastructure for life science and technology companies with complex operational needs. The Assembly Innovation Park campus was designed with large floor plates, integrated amenities, and the ability to support advanced research, development, and manufacturing programs.
“We are delighted to welcome TransMedics to BioMed Realty’s highly differentiated Assembly Innovation Park campus,” said Bill Kane, President, East Coast and U.K. Markets at BioMed Realty. “Led by our team of multidisciplinary experts, BioMed’s hands-on approach allows us to create and manage spaces that support our tenants’ most strategic initiatives.”
Assembly Innovation Park is located within the Assembly Square district of Somerville, offering access to Interstate 93 and the MBTA Orange Line. The location provides direct connectivity to Greater Boston’s academic institutions, clinical centers, and life sciences talent base.
“At BioMed Realty, our purpose is to deliver mission-critical infrastructure that enables innovators to focus on advancing technology to improve human health,” said Colleen O’Connor, Executive Vice President, Market Lead, East Coast & UK Markets at BioMed Realty. “The Assembly Innovation Park campus was designed to provide flexibility and operational resilience that companies like TransMedics need to accelerate innovation and change lives.”
