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.


Welcome to the 2020-21 school year! I know this school year will be different than ones in the past but I am so happy to have most of our students back at Defino in a Hybrid Learning Model. I am available during regular school hours from 8:20 am to 3:10 pm, Monday through Friday, to answer questions or address any concerns you or your children may have. I can be reached via telephone at 732-972-2099, ext 6259 or by email at [email protected].  We are here to support your children and the community during these difficult times. 


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!
