This National Association of Home Builders' professional designation is exclusively designed to emphasize business management skills as the key to a professional remodeling firm. To obtain this designation, one must have a minimum of five years experience in the remodeling industry and complete coursework suitable for this exclusive designation. This designation teaches the technical and customer relations skills essential to compete in the fastest growing segment of the remodeling industry: Home modifications for the aging-in place. These modifications enable homeowners to remain safely and comfortably in their OWN HOME. Hands on experiences are used to illustrate and gain a better understanding of the struggles one could face and brings them to real life. 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, the CGR designation, or the CGA designation with five years of building experience, or ten years of building experience and have completed three CGB/CGR/CGA courses. GMB courses are more advanced with in-depth instruction geared for experienced building professionals. The National Association of Home Builders' Certified Green Professional designation recognizes builders, remodelers and other industry professionals who incorporate green building principles into homes- without driving up the cost of construction. Classwork leading to the designation provides a solid background in green building methods, as well as the tools to reach consumers, from the organization leading the charge to provide market-driven green building solutions to the home building industry.
