Principal’s Welcome to the Mount Sinai Middle School Website

Welcome to Mount Sinai Middle School! 

Mount Sinai Middle School provides middle level education to students in Grades 5 - 8 in the Mount Sinai School District.  Together with our dedicated staff and supportive community, my goal is to ensure that each student enjoys a fulfilling and memorable middle school experience and embraces the special nature of living and celebrating #MustangPride. 

Serving as building principal in the community where I grew up as a K-12 Mount Sinai student fills me with immense pride and enthusiasm.  With nearly 17 years in education, including roles as a high school business teacher and assistant principal, I’m deeply committed to fostering a positive, inclusive, and engaging learning environment.  My experiences as a Mount Sinai student inspire me to uphold and enhance our district’s tradition of being “the best in learning and living.”

At Mount Sinai Middle School, members of our living community adhere to our “Code of Expectations” called “Mustang Manners!”  This framework commits to three core expectations:

STAY TO THE RIGHT

BE POLITE

KEEP IT CLEAN

These core values are integrated into daily student life, empowering every student to achieve academic and personal growth; preparing them for future success.  When practiced accordingly, this code exemplifies our building’s vision of “Celebrating #MustangPride.”  

Family is central to my life, and I am committed to fostering strong partnerships between school and home.  Please stay informed with our administrators, faculty and staff through our ParentSquare platform.  

As always, please feel free to reach out to me directly with any questions, concerns, or simply to introduce yourself.  I can be reached via email at celsesser@mtsinai.k12.ny.us or telephone at (631)870-2700.  I am here to listen and collaborate with you to ensure that your child thrives at Mount Sinai Middle School.

Warm regards,

Christopher H. Elsesser
