Simple Serenity Retreat

The 2024 retreat will take place in person September 27-29 at St. Dorothy's Rest in Camp Meeker, California. Registration is expected to open in August 2024, please check back for details.


Thank you a million times to the planning team. This was my first retreat and I had such growth, sisterhood/brotherhood, a feeling of such love and being loved with all COSAs. Good balance of me-time and friend-time. Every workshop was brilliant. BIG GRATITUDE."

2024 - Join us for a weekend of recovery and fellowship 

For the past eighteen years, Northern California COSAs have gathered to share their stories, their recovery, and their support with each other over the course of a weekend in a cozy retreat environment. Past retreats have included  12-Step meetings, speakers, workshops, fellowship, delicious meals, and opportunities for meditation, crafting, and communing with nature.

This year we will meet again at St. Dorothy's Rest on the weekend of September 27-29, 2024. Registration will open in August 2024. For a sense of what you might expect at the retreat, please view last year's program.

We look forward to seeing you at the retreat!
