WELCOME TO THE OSCEOLA YMCA We’re committed to improving the lives of all of our members throughout Osceola County and Central Florida! Our family center is located on West Mabbette Street, between Thacker Avenue Elementary School and the Kissimmee Gateway Airport. We’re a vital part of the community for thousands of members—infants receive childcare, teens have a safe space in our Teen Center, adults get personalized attention with our personal trainers, and seniors stay healthy with our Active Older Adults programs. As a leading nonprofit, we work side-by-side with our neighbors to make sure that everyone has a place to learn, grow, and thrive.
