The Treasure Island Community

Making Positive Changes for our Community​

The singular focus of the Treasure Island Community YMCA is the health and wellness of the community itself. With 89% of families living below poverty, no elementary school in the area, and very limited extra-curricular programming offerings, the youth and families residing on Treasure Island (TI) need opportunities to enhance cognitive growth and physical and mental well-being. In 2013, the Treasure Island Community YMCA became the main provider for Health and Wellness for all families living on Treasure Island and have been growing and developing programs and opportunities for the community since; free of cost. Offering health and wellness class, nutrition tips and open gym space for the adult and teen population as well as providing several youth programs and opportunities during Out of School time such as after-school, weekends enrichment sessions and summer camps. Believing that communities are a source of rich expertise and human capital, we also focus many efforts on community engaging by hosting family engagement opportunities and collaborating with other partners on located on Treasure Island to support the needs of the community. The Treasure Island Community YMCA believes that by investing in the future of individuals and their communities, providing platforms for those individuals to effect change in themselves, in the built and natural environments in which they live, and in our society as a whole.

Since 2006, the Embarcadero YMCA has teamed with the Treasure Island Development Authority (TIDA) to bring YMCA programming and facilities to the residents of Treasure Island. Our goals are to provide space for the community to build strength, find balance, and gather as a community. We offer free programming for youth and adults all year and employ a dedicated Y-staff invested in ensuring the safety and growth of the community.
