School Social Worker

on the Child Study Team



My name is Karyn Tessler. I am currently the School Social Worker at Defino Central Elementary School. I have been a proud member of the Marlboro Township Public Schools since 2016.  As the School Social Worker, I have the pleasure of supporting students' academic and social/emotional learning. Collaboration and communication is the key when working with parents, staff, and administration to ensure student success.


Since each student in the district has been placed on home instruction due to COVID-19, all students are receiving assignments through their teachers' Google Classroom.  I will also be online and available by email at from 9:00 am to 1:00 pm, Monday through Friday, to answer questions or address any concerns you or your children may have.  We are here to support your children and the community during these difficult times. 


Please feel free to email me at:


Please feel free to explore the attached resources I have provided under the Links and Resources page. I will be adding social/emotional and behavioral supports throughout home instruction. Please check back frequently or email me specific questions or concerns. Stay safe and healthy!
