2025 15U - 18U Girls' Open Gyms
All Summer Open Gym events for 15-18U are now finished. Additional open gym for 18U prior to the now-rescheduled tryouts in November to be announced at a later date. Thanks to all who signed up and participated in these valuable sessions.
Is it Mandatory to attend open gyms before tryouts? Mandatory? No. Strongly encouraged? Absolutely! At TNT, we pride ourselves on offering fair tryouts where all players have a chance to make all teams. If you are new to TNT, and no TNT coaches know you, it is STRONGLY recommended to attend multiple Open Gym events to get to know the coaches and have them get to know you. The easiest way to get overlooked at tryouts is to never have been seen by a coach or the club. Trust us...it helps.
Playing age is determined based on the table at the bottom of the page.
Open gyms are a FREE way to check out TNT. There is no TNT fee to participate in an open gym. However, AAU membership is required for insurance reasons. AAU Memberships from last year/season expire on August, 31 so a new one will need to be purchased. When doing so, please associate membership with Club Code W34DED.
To obtain an AAU membership click here. Choose "Youth Athlete Membership", "Regular". AAU membership runs from 8/31/2025-8/31/2026.
