Charity Zawatski - Executive Director

Charity Zawatski is joining our school family from Upstate New York.  Charity is relocating from Brownville, NY with her family and her Great Dane, Jazmine.   She has worked in public education for the past 23 years. Charity attended Florida Southern College where she earned a B.S. in Biology with marine science. While traveling abroad for a semester and completing the Semester at Sea program, Ms. Zawatski was inspired to become a teacher and started the MST program at SUNY Potsdam to earn a Master's Degree in General Professional Education to become a teacher. Ms. Zawatski started her career as a French and Science Teacher for eight years before venturing into administration.   

At that time, Charity attended SUNY Oswego to earn a Certificate of Advanced Study in Educational Administration.  She has served as a Reading Coach, Professional Development Specialist, and Teacher Trainer for schools in need of improvement. While in Syracuse, Charity worked in the field with superintendents and administrative teams on both strategic and corrective plans. She also spent much time directly in the classroom coaching and modeling best instructional practices with teachers and students. Ms. Zawatski then transitioned into a school principalship where she has spent the last thirteen years.   She has experienced building closures, district restructuring, and much change over that time.   She has rebuilt grade-level teams, led and supported inclusive and differentiated instruction.  Charity is passionate about being a lifelong learner as she is currently a doctoral candidate through Nova Southeastern University completing her doctorate this fall.   Charity has worked at all levels within the UPK-12 realm of education and brings diverse experience to the team and school.
