• FamilyID is a secure registration platform that provides you with an easy, user-friendly way to register for our programs, and helps us to be more administratively efficient and environmentally responsible.

  • Parents/guardians register through FamilyID, entering accurate and up-to-date health history for each sport in which a student athlete participates. This provides the school athletic trainer with the most current information regarding concussions, injuries, or circumstances that may affect a student athlete since their last physical examination and/or sports season. Enrollment in FamilyID indicates parental consent for participation.
