Established in 1948, North Bay Credit Union is the oldest credit union in Sonoma County and was originally called Sonoma County Grange Credit Union. It was founded by members of Sonoma County Granges who pooled their savings to help new farmers who had no access to bank credit so they could buy land and equipment to start their own farming operations. Over the years, we expanded our membership to include all residents of Sonoma County, and recently changed our name to North Bay Credit Union.
