About Us


Bob Rosenberg

Born and raised in New York, Bob moved to the Bay Area in the seventies with a B.A. in Business Administration. Like many successful entrepreneurs, his business began by mastering the basics. While an apprentice in the Carpenter’s Union, Bob discovered his passion for high end remodeling. As he worked throughout the peninsula, Bob was personally trained by master carpenters from Finland, Sweden and Germany who taught him how to do it right.
In 1977 Bob founded GR8WORK Builders. In the early years, Bob did every stage of the project himself. This first-hand experience taught him that perfection only happens when all the details integrate with each other. As the company grew, employees were trained to approach each job in the same conscientious manner.

This passion for perfection led to affiliating with other trade contractors who cherish quality, service and have an extensive knowledge of remodeling. More than thirty nine years later, Bob still surrounds himself with those who pay attention to detail and know how to integrate their skills with other team members.

NARI, the National Association of the Remodeling Industry, awarded him the highly acclaimed level of Certified Remodeler. Bob is also a Certified Green Building Professional, incorporating sustainable design and environmentally friendly practices into his business.
He is now a Universal Design Certified Professional and has the skills to advise clients of all ages and abilities about ways to remain in their homes.
