We are the largest and most experienced full service commercial real estate company in the North Bay. Since our founding in 1976, we have been providing brokerage services to the areas of Marin, Sonoma, Napa, and Solano Counties. Our four offices are located in Santa Rosa, Petaluma, Napa, and Larkspur.

With our experience in leasing space, build-to-suits, selling land and buildings, we can successfully meet your real estate goals. We also network nationally through the most prestigious of organizations; the SIOR (Society of Industrial-Office Realtors) Oncor International provides our regional, national, and worldwide platform to represent our clients anywhere they may wish to buy an investment or obtain a new location. Regionally we have relationships with other companies that go back 36 years.

Keegan & Coppin Oncor International also has one of the largest commercial property management divisions in the North Bay. We also have construction, ranch, land, and estate marketing divisions. Marketing today requires more of a consulting approach and a thorough grounding in contracts, leases, environmental law, municipal processing and construction. Our marketing experience allows us to anticipate problems and come up with creative solutions before they arise. Our technical ability in all areas of real estate is our foundation.
