Rohnert Park-Cotati has 3 Rotary Clubs - Meet Ours!

Founded in 2021, the Sonoma Mountain Twilight Club meets twice monthly in the evenings for the purpose of making friends and engaging in community service projects. This year we are celebrating our 5th Anniversary by reinstating the Rohnert Park Founders Day! We love this event because it provides a fun community-building opportunity, and participation fees provide our main fundraiser of the year, enabling us to support many community-based charity activities.

We'd love to have more members in our club! It's fun! Please visit any meeting to discovery how rewarding Rotary participation can be!

Rohnert Park Founder's Day is a living history of community spirit. We celebrate our history of producing this event numerous times, bringing strangers and neighbors together in the spirit of fun and community support.

To find out more about the Sonoma Mountain Twilight Rotary CLub, which meets the 1st & 3rd Thursday eveningof each month, contact RPFoundersDay@gmail.com.
