For youth development

Dedicated to Today's Youth

Whether developing skills and encouraging volunteerism through youth programming, welcoming and connecting diverse demographic populations through membership and services, or preventing chronic disease and building healthier communities through collaboration, the Y empowers people in our communities to be healthy.

For healthy living

Focusing on healthy living

Being healthy means more than simply being physically active. It’s about maintaining a balanced spirit, mind and body. The Y is a place where you can work toward that balance by challenging yourself to learn a new skill or hobby, fostering connections with friends through our lifelong learning programs, or bringing your loved ones closer together through our many family-centered activities. At the Y, it’s not about the activity you choose as much as it is about the benefits of living healthier on the inside as well as the outside.

For social responsibility

Driving social responsibility

The generosity of others is at the core of the Y’s existence as a nonprofit. It is only through the support of our hundreds of thousands of volunteers and public and private donors that we are able to support and give back to the communities we engage.
