The Parent Teacher Organization
The Parent Teacher Organization (PTO)’s mission is to strengthen parents’ and teachers’ understanding of our children and how they learn as individuals while promoting the advancement of Catholic education and family life. The PTO hosts various activities throughout the school year that benefit students and their families. In addition, we do various fundraisers to help raise money to bring needed textbooks, technology resources, learning opportunities and improvements to the school. The PTO is organized under the authority of Father Ed Bresnahan and operates in accordance with the guidelines established by Saint Leo the Great Parish and the Diocese of Arlington.
All volunteers must be OPCYP compliant. Questions?
Contact Mrs. Maguire at smaguire@saintleothegreatschool.org or call the school office at 703-273-1211.
