Our History

Founded by principals of three Southern California real estate developers, G Companies has over 70 years of development and property management expertise in the residential and commercial real estate markets. We have collectively built over 60,000 homes and 7,000 apartments in California and the Southwestern United States.

G Companies, owned by the Gianulias', began developing properties in California nearly seven decades ago. Despite four major recessions that forced many builders to close their doors, the Company has continued to build and expand without interruption since 1968. 

From the seeds of Hester Development in 1949, Cameo Homes for several decades there after, the family tradition of real estate development and construction has grown and distinguishes itself through its branded development projects, Silver Oaks Communities. G Companies has earned a reputation for quality, integrity, embracing new ideas and delivering traditional craftsmanship of our developments. From affordable starter homes and condominiums to luxury homes and estates. Today, the G Companies distinctive mark can be seen throughout the United States.

G Companies diverse building accomplishments include the development of approximately 60,000 single-family homes, condominiums, and townhomes, as well as over 7,000 market-rate multi-family and senior units. They have also developed several commercial/retail/office buildings, various ranch properties, golf courses and wineries throughout Northern, Central and Southern California, Arizona, Nevada, Texas and New York.

Mesa Management is the property management division of the company. Mesa manages the many market-rate multi-family and senior complexes as well as the commercial/industrial developments currently in operation in Southern California.

The Gianulias family has branched out to the wine producing industry and also owns Chardonnay Golf Club where Levendi grapes are grown and harvested, as guests golf the 18 holes that overlook the vineyards. Levendi is served exclusively in several upscale establishments throughout the United States.
