Our Communities

As a community bank headquartered in Santa Rosa, Summit State Bank specializes in providing exceptional customer service and customized financial solutions to aid in the success of local small businesses and nonprofits at five Sonoma County branches located in Petaluma, Rohnert Park, Healdsburg and two in Santa Rosa. At Summit State Bank we embrace a culture of giving back to those in need and we take great pride and responsibility in support of our Nonprofit Partners. Our Nonprofit Partner Program pays a preferred interest rate on operating accounts for participating nonprofits. We also encourage our employees to give back to the community we serve through our Summit Day of Service program. This program gives every employee one workday a year to volunteer their time on behalf of the Bank with any nonprofit organization in Sonoma County that they feel passionate about.

Santa Rosa - Bicentennial

We have two branch locations in Santa Rosa – our Corporate Headquarter is located just off highway 101 in northern Santa Rosa. The iconic building is visible as it sits on Bicentennial Way, a main thorough fare, across from Kaiser Hospital and a primary artery to the Fountaingrove community. Located on the first floor, just off the building’s lobby, the Santa Rosa Main Office welcomes customers with friendly customer service representatives at a traditional teller line as well as desks for customers to conduct business. Our other Santa Rosa location is in Montgomery Village, a shopping center in east Santa Rosa.
