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

Our Petaluma office reflects the expansion and legacy of Pisenti & Brinker LLP, a firm founded in 1962 and long recognized as a trusted advisor in California’s North Bay. That same commitment to personal service, technical excellence, and local insight continues today as part of Sorren, with even more ways to support our clients’ success. Throughout its evolution, Pisenti & Brinker stayed committed to delivering high-level service with professionalism, care, and deep local insight. Today, as part of Sorren, that tradition continues with even broader resources and reach.

Our Culture & Community

We’re proud to be part of the Petaluma community and the greater North Bay region. Our team combines technical excellence with a strong commitment to serving our clients, colleagues, and community. Staff regularly volunteer with local organizations, participate in civic and charitable events, and serve on nonprofit boards. Many of our professionals have been honored for their leadership and impact across the region, reflecting a culture that values involvement, integrity, and continuous growth. In Petaluma, our work is personal, and our commitment runs deep.
