A Brief History of Cotati Chamber

The Cotati Chamber of Commerce is one of the oldest community organizations in the area, and has been promoting and serving local businesses since Cotati was little more than a railroad stop.

Originally known as the “Cotati Promotion Club,” the group formed in the early 1900s to provide support services for a township that grew out of the distribution and sale of land belonging to the Page family. The Cotati Promotion Club shed its name circa World War I, opting to be known as the “Cotati Chamber of Commerce.”

The transformation of Cotati into a vibrant community came rapidly with the Cotati Chamber as an active participant. The Lions Club took over the civic functions of the chamber during the Great Depression, but the chamber was reactivated as a business organization in 1940 and incorporated in 1958.

Today, the Cotati Chamber continues to promote the community and help attract new businesses — from helping (in the late 1950s) to establish Sonoma State College to starting the Cotati Farmers Market, to producing popular events such as the Cotati Jazz Festival, Oktoberfest and Holiday Cheer. Additionally, monthly ribbon cuttings for new businesses and mixers for existing Chamber businesses bring attention to the thriving small business community in Cotati.
