The Sierra County Chamber of Commerce is a County-wide Chamber comprised of businesses, individuals and organizations working together to promote our beautiful Sierra County. The Chamber publishes an annual Visitors Guide that is a great reference for visitors and residents alike. Membership includes advertising for your business in the guide, on the chamber website, and through social media. The Chamber works hard to stimulate the local economy and support each other because a strong small business community benefits the entire county.
