What Tsoi Kobus Design does
Tsoi Kobus Design is a Boston-based architecture and interior design firm founded in 1983, specializing in healthcare facilities, higher education campuses, science and technology research buildings, and commercial developments. The firm operates six core practice areas — Science + Technology, Healthcare, Higher Education, Proton Therapy, Commercial Development, and Interiors — with a particular reputation as one of the most experienced designers of proton therapy centers globally, having delivered 40+ such facilities. Notable projects span the $2.5 billion Henry Ford Health expansion in Detroit, Moffitt Cancer Center's 775-acre Speros FL campus, Boston Medical Center's Yawkey Inpatient Expansion, Penn Medicine's Roberts Proton Therapy Center (the world's largest proton facility integrated into an academic medical center), and 22-story Center for Life Science Boston for BioMed Realty.
The firm's revenue model is professional services-based, generating fees through project-based architectural commissions for enterprise clients. Work is won through competitive RFP processes, direct commissions from long-term institutional clients (including 10+ year relationships with Henry Ford Health and repeat engagements with Boston Medical Center and Moffitt Cancer Center), and referrals within the healthcare and higher education sectors. Differentiation rests on specialized technical expertise in proton therapy facility design (cyclotron vaults, shielding, treatment room integration), Post-Occupancy Evaluation methodology, and a portfolio of 100+ design awards from organizations including AIA, CMAA, ULI, and the Boston Society of Architects. The firm uses standard industry digital tooling — Building Information Modeling (BIM) overseen by a dedicated Director of Digital Design — but operates without proprietary AI/ML or technology products.
In 2023, Tsoi Kobus Design was acquired by DLR Group, integrating its specialized healthcare and research facility expertise into DLR Group's national architecture and engineering platform while maintaining its dedicated Boston practice and proton therapy specialization. The firm serves national markets across the Northeast, Southeast, Midwest, Southwest, and West US regions, with prior international engagement in Singapore. Operating headcount is in the 51-100 range per firmographic data, with ~35+ staff listed on the company website. Founding principal Edward T.M. Tsoi passed away in 2023; co-founder Richard L. Kobus continues as Founding Partner and Senior Principal.
