family owned & operated Since 1977.

SUMAC Construction was founded by Keith and Stuart Giebelman. Based in San Diego, the brothers started out as spec home developers and builders. In time, their interests moved to the luxury home market, which was heating up as more people migrated to San Diego’s beauty and climate. Building many spectacular homes in these areas grew SUMAC’s reputation as an expert in the custom home market.

Keiths son Dan started in the construction trade at age 16. His father and uncle taught him every phase of construction operations, including estimating, project management, scheduling and value engineering. In 2019 the board of directors voted Dan as CEO.

Under his leadership, SUMAC grew to be one of the largest custom home contractors in the greater San Diego area with over 300 homes in their portfolio.

SUMAC’s family ideals of honesty, integrity, their obsession for quality control and work site safety continue to guide the entire SUMAC organization on a daily basis.

The SUMAC family could never have achieved the success we’ve had without the expert help of our extended family of employees, architects, and subcontractors. Thank you for carrying out our ideals of honesty, integrity, and construction quality.
