The Trinity Charger Alliance is composed of parents who work together with the faculty, staff and administration of the school. The governing body of the TCA consists of elected parent volunteers representing academics, athletics and fine arts.
The purpose of the Trinity Charger Alliance (TCA) is:
To promote goodwill and enhanced communication among parents, teachers, school administration and trustees.
To provide volunteer and financial support to Trinity School through special projects.
To promote positive public relations for Trinity School.
The Trinity School Gala is the biggest event of the year for the TCA. This large fundraiser allows the TCA to continue to provide gifts that benefit the entire school.
In 2022, Setsubun, An Evening in Japan, netted over $550,000.
