Graduate Master Builder (GMB)

The ultimate symbol of the building professional, the Graduate Master Builder (GMB) designation is for experienced veterans only. Before beginning the GMB designation process, you must have the CGB designation or the CGR designation with five years of building experience, or 10 years of building experience and successful completion of three CGB/CGR courses.

GMB courses require additional study, with in-depth instruction geared for experienced building professionals. It’s a significant time commitment, but graduates gain a more complete knowledge of all facets of the home building industry, build a new network of peers across the country, and inform their potential clients of their commitment to the best of home building, customer service and advanced construction techniques.
