*You must provide a copy of your child's current physical exam before they will be eligible to participate. You may turn in a hard copy to the office or upload a copy to Family ID.  A legible cell phone picture will work. (helpful guides attached at the bottom of the page!)
*Our fees can be paid online (  If this in not an option, please pay Lisa in our bookkeeping office.
