The J.B.M. name was built on a solid reputation for integrity and workmanship strengthened through the personal envolvement and committment to each project by the founder, John C. Bonenfant. 

J.B.M. began by providing carpentry services to educational institutions in the Boston metropolitan area.  Today, our services have expanded from simple carpentry to more complex construction renovations. 

Our portfolio includes constructing administrative offices, student lounges, classrooms, conference rooms, complex labs and sound recording studios.
