The Mamaroneck Schools Foundation (MSF) is an independent non-profit organization whose mission is to enhance the quality of public education in the Mamaroneck Schools by funding innovative programs that fall beyond the scope of the regular school budget. By engaging the support and energies of the community, we raise funds for the awarding of grants to our teachers, members of the school administration, and students. Since our founding in 1996, MSF has funded over 500 grants, totaling more than $5 million to the Mamaroneck school district which enriches the education of all students.  That’s all thanks to you and your enthusiastic support.  Consider an additional donation of any amount to help us continue to inspire innovation in our students and teachers.  THANK YOU. THANK YOU. THANK YOU.
