Celebrating 90 years of advocating for children in Hillsborough County. Established in 1924 and organized under the authority of the Florida PTA, each school's PTA/PTSA is a team of volunteers dedicated to strengthening local PTAs and PTSAs in Hillsborough County. The PTA / PTSA works on behalf of the children in their schools and communities. Together, we form a strong, unified voice on behalf of the children in Hillsborough County.
