Teamwork for Tam
Parent volunteers are elected to serve two-year terms. The board meets monthly during the school year. Members support the annual giving campaign (AGC,) grants evaluation, and communications. There is an opportunity for every parent to get involved, and we welcome and value ALL perspectives and experiences. New members are recruited each spring.

Representatives provide guidance, insight, and knowledge from across the campus. They are non-voting members and work in close partnership with the executive board.

This is my 7th year as principal at Tam High. I enjoy working with the Foundation because it provides unique educational experiences for our students. Through THF, we can innovate and create meaningful learning opportunities that extend beyond the regular curriculum.
