Trevian Girls Softball Association


The TGSA was originally established in 1980 to provide a top quality softball program for girls residing in the New Trier Township. The organization has since evolved to welcome players from neighboring and nearby communities as well. TGSA strives to maintain a strong base of community players in the organization, while also opening its doors to players from nearby areas seeking a top quality softball program.

TGSA is a non-profit organization run primarily by parent volunteers.  Through participation in the Trevian program, its players learn responsibility, hard work, teamwork and how these things add up to group success. Trevian players also build self-esteem and the confidence to take on difficult challenges later in life.
