Chair & Treasurer

After growing up on the beaches of Southern California, Spencer moved to Sonoma County to attend college. While exploring the local surfing opportunities he was awestruck by the raw power of Sonoma’s coastline and knew that its unique beauty should be preserved and protected. 40 years later Spencer has focused his support for this rugged stretch into environmental activism as Chair of Sonoma Coast Surfrider Foundation.

Sarah Heyne


Vice Chair, Chapter Secretary & RAP Coordinator

Sarah is the Vice Chair and Secretary for the Sonoma Coast Chapter and she developed a passion for the ocean while exploring the Santa Cruz area as a child. She first became involved with Surfrider after participating in the Marine Debris Community Outreach Program with the Monterey chapter. This sparked her interest in the issues surrounding plastic pollution and she continues to work with Sonoma Coast Surfrider to advocate for responsible solutions to environmental issues along our coast.

Arline is a water sport enthusiast and became involved with Sonoma Coast Chapter Surfrider Foundation five years ago. Initially, she focused on fund-raising and organizing our annual Blue Water Paddle Race. Now, she is happy to be volunteer coordinator recruiting new members, supporting beach clean-ups and working with local students as they pursue environmentally oriented careers.

Gregory Fearon


At-Large Member

Born in La Jolla, California in the late 1940’s, was wading into the shore break at the age of four, participating in surfing contests in junior high, and started the first state-sanctioned High School Surf Team in 1964.  Unfortunately, those surfing memories are long ago, and his water sports now are confined to swimming and sailing. Greg assists the Chapter in all fund-raising efforts and has been especially helpful in making our annual Blue Water Paddle Race a success.
