Arline Thomas

Volunteer Coordinator

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.

Karen Groff


I am a paraprofessional at Rancho Cotati High School. I love to bake. I visit the beach often and clean up trash every time I go for a walk. I have a daughter who is a sophomore at U.C. Santa Cruz. She and my husband, Scott, also love to clean the beaches with me. Hawaii is our favorite vacation spot, followed by Lake Tahoe.



Sarah 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 in 2010. 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 beautiful coast.

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. Gregory assists the Chapter in all fund-raising efforts and has been especially helpful in making our annual Blue Water Paddle Race a success.

In loving memory of two great Sonoma Coast Surfrider leaders we lost in 2019. Your passion for the coast lives on within our chapter.
