A little bit about us

In 2012, the One All founders recognized a need in the community for fun and safe opportunities for youth to be active in the after school hours. We saw the deficiency in fitness and shortage of health and wellness education for youth.

Two alarming statistics jumped out at us:
1. Childhood obesity is on the rise.
2. Millions of middle school kids are unsupervised after school.

One All was founded to teach the skills of a lifetime sport to our youth. One All is building a culture of fun through after school programs to give youth the tools to live a healthy lifestyle and transition into productive members of their community. We believe that the One All culture will foster a sense of community and kindness of heart that will make the world a better place.

The One All Team is having a blast sharing our love of sports and knowledge of leadership, health and wellness with the community. We hope you will come out for a season of One All Tennis or join us in our effort to champion the cause of giving all youth the tools to live a healthy lifestyle, the skills to make their dreams a reality, and the kindness of heart to make the world a better place.
