Calvin Natt is the founder and Executive Director of “All For One-One For All” non-profit foundation. During his playing days in the NBA he often visited hospitals to see kids who were ill. During a remote broadcast with a radio station at the Children's Hospital last year, Calvin's vision to start a foundation designed to provide burial assistance to parents with deceased children became a reality.
