Welcome to California
There are more than 50 million Americans with Arthritis - 5,953,000 of them live in California. The Arthritis Foundation is the Champion of Yes. We are focused on finding a cure and championing the fight against arthritis through vital information, advocacy, science and community. Our goal is to chart a winning course, guiding families in developing personalized plans for saying yes – day after day.
Join us at the 52nd Annual Knowles Lecture. Keynote speaker, Dr. John H. Stone presents "What Is IgG4-RD (And What Is Not IgG4-RD) and What Does It Tell Us About The Immune System". Registration is required.
Our Walk to Cure Arthritis is the largest arthritis gathering in the world, celebrating our warriors, raising funds for research, resources and a cure. Whether you’re an arthritis warrior yourself or care about someone who is, sign up and WALK to CURE Arthritis.
