Welcome to the Dulles Elementary PTO Website! The Dulles Elementary School PTO stands for Parent Teacher Organization. We collaborate with parents, volunteers and school personnel to enhance each child’s educational experience through fundraisers, family events, school clubs and much more! Our volunteer hours and fundraisers assist the teachers and staff in providing the best opportunities for our Little Vikings. We hope that you will join our efforts in making Dulles Elementary a great place of learning and fun! Come join us!
