Tom Bachman, AIA Principal

As a founding partner of gbA, Tom is strongly committed to Vermont and New England communities and citizens. He believes architecture is a vehicle to connect people and places, and, for over thirty years, has enjoyed designing affordable housing projects, schools, libraries, and other community resources across New England. His projects’ successes can be attributed to not only building design, but also the cultivation of strong client/architect/contractor relationships.

Tom has volunteered at the Central Vermont Good Samaritan Haven Homeless Shelter for over twenty years and currently serves as Treasurer on the Board of Directors.
