Santa Rosa, California

Our Vision

We’ve come together to serve our clients through every stage, every idea, every challenge, no matter their size. We’ve expanded specialties while preserving what matters most, your relationship with the professionals you know and trust. Our team now offers a broader range of services, backed by deeper resources and specialized expertise across tax, assurance, advisory, accounting, and private client services—all delivered with the personal attention that has defined our legacy firms for decades.

Our History

With nearly 60 years of history, our Santa Rosa office reflects the legacy of Pisenti & Brinker LLP, one of the most trusted accounting firms in California’s North Bay region. Founded in 1965 by Edward J. Pisenti and Lynn Brinker, the firm grew steadily with strategic partnerships and mergers, expanding into Petaluma and serving clients from Sonoma County to the East Bay. Throughout its evolution, Pisenti & Brinker stayed true to its founding values: delivering high-level service with professionalism, care, and deep local insight. Today, as part of Sorren, that tradition continues with even broader resources and regional reach.

Our Culture & Community

We’re proud to be part of the fabric of the North Bay. Our Santa Rosa team blends technical expertise with a genuine commitment to our clients, our people, and our community. Staff actively serve on local boards and volunteer for organizations such as the Redwood Empire Food Bank, while also participating in company sports leagues and community events. Our professionals have been recognized with honors such as NBBJ’s Forty Under 40, YPN’s Young Professional of the Year, and CalCPA’s Women to Watch, underscoring a culture of leadership, engagement, and excellence that extends well beyond the office walls.
