Developing Successful Players and Even More Successful Individuals

Trevian Girls Softball Association teaches juniors to 18U girls basic, intermediate and advanced softball skills, which they are able to practice in league play and competitive tournaments. The Trevian Girls Softball Association (TGSA) experience provides players with the knowledge of the game required to play at the high school level and beyond. Over the years, TGSA has afforded many of our players the opportunity to be recruited by top colleges.

Most importantly, participating in our programs helps young girls grow as individuals and team players – on and off the field – and gives them core life skills they will treasure and utilize forever.


Through softball, we teach responsibility, teamwork, work ethics, and self-esteem so our players can grow to be confident, successful individuals.


Thanks to our team training, private coaching, workshops, and skills clinics, many Trevian players go on to have very successful softball careers at top colleges.


Many of our alumnae come back to offer leadership and mentoring to younger players. This is a testament to the impact the program has made on their lives.
