In support of this approach, Tuna has served on the LMS Board for several years and is going into her second year co-leading the Parent Engagement Committee. Tuna also serves on several boards for area nonprofit organizations whose missions focus on children and community-building -- a deeply held passion that started while pursuing a BA in History at Haverford College, and continued at Northeastern University, where she received her JD.
