Exchange Bank Announces Grand Opening of Marin and Petaluma Branches

PETALUMA, Calif.–(BUSINESS WIRE)–Exchange Bank (OTC: EXSR) is pleased to announce the grand opening of two full-service branch locations as part of its ongoing commitment to expanding access to personal, relationship-driven banking across the North Bay. The new branches—located in San Rafael and Petaluma will offer a complete suite of consumer and business banking services, along with the trusted community-first approach that has defined the bank for more than 135 years.

The addition of the full-service Marin Branch located at 3950 Civic Center Dr suite 101, San Rafael, CA 94903, will allow Exchange Bank the opportunity to provide enhanced services for the local and business community, building on the previous Trust and Investment Management presence. The Marin Branch operates Monday through Friday from 9:00 a.m. to 12:00 p.m.

The beautifully designed new Petaluma West Branch has been relocated to 200 Kentucky St, Petaluma, CA 94952. The location offers a first glimpse of the new vision for the next generation of Exchange Bank. This expansion reflects not only strategic growth, but also a deep continuation of the bank’s mission to invest in local neighborhoods, strengthen economic opportunity, and build relationships that last for generations.

“Exchange Bank has been serving the Petaluma community since our first Petaluma branch opened in 1973 and similarly, we have been offering our wealth management services in San Rafael since opening the office in 2023,” said President and CEO Troy Sanderson. “While we have been established within these communities for years, we are thrilled to expand our services to better meet the needs of our customers.”

Each new location will feature a modern customer-centric design, meeting spaces, and a dedicated team of bankers rooted in the communities they serve.

“With every new branch, we reaffirm our belief that strong communities and strong local banks go hand in hand,” added Troy Sanderson “My hope is that these branches become a catalyst for opportunity, connection, and continued growth for families and businesses across the area. We’re not just opening doors—we’re opening possibilities.”

Both new branch locations opened in December 2025 with grand opening celebrations planned for the new year.
