Committed to Your Wine Business

If you’re looking for custom financing solutions to help grow your wine business, look no further than the team of industry specialists at Bank of Marin. Our local, expert lenders can provide flexible lending solutions for your wine-related banking needs including vineyard development, construction financing, commercial real estate, and barrel financing.



Take Control of Your Finances, with Confidence

With relationship banking as our guiding principle, we put you first at every stage of life. This includes helping you navigate the complexities of establishing trusts, wills and healthcare directives. At Bank of Marin our role is to guide you at the right time, to help you answer your most pressing questions and concerns, and to anticipate your needs before they become an unnecessary burden to your family or your business.

There can be some confusion about how a trust is different from a will and who needs one. Most people need a will and a healthcare directive as part of a basic estate plan. We can help you analyze your assets to determine if the cost of creating and maintaining a trust is justified. For those who already have a trust, we can also help determine if your trust needs updating.


We can help manage your wealth and protect your legacy.

Legendary Service

Twenty-one years after its founding in the North Bay, Bank of Marin opened its first brick-and-mortar in Napa. While the Bank has proudly been part of the fabric of the community since 2011, its employees have a much deeper-rooted history that collectively spans more three centuries.

The team—comprised of approximately 30 retail and commercial banking employees who live in and/or work in Napa— provide financial services to Napa-based government agencies, private and public schools, the wine sector, and health and wellness industries, to name a few. It is the Napa team’s dedication to the community and its customers that has earned the Bank the recognition of Large Business of the Year by Napa Chamber of Commerce.
