Mahwah Middle School

Sage Day’s Mahwah NJ Campus is a state of the art learning environment that fully integrates therapy throughout the school day.


Welcome to Sage Day Lower & Middle School. Thank you for taking the time to learn more about our program and the important work we do every day for the students we serve. I first began Sage Day as a Clinician prior to becoming the Clinical Director in September of 2019 and I fully believe in the program we have to offer. I am passionate about the work we do at Sage and I am committed to making this a program that is always first and foremost student-centered. Please don’t hesitate to contact me to discuss our program further or how we may meet the needs of a specific child you have in mind.

Clinical Director

The Sage Day Lower and Middle School brings me tremendous pride and satisfaction when I watch in awe the progress that our students continue to make in their participation in learning, emotional growth and social development. The Sage Day family of therapists and teachers work as one collegial community to serve and support the needs of students and their families every day. Over time, students who once found attending school to be an ominous task routinely attend and thrive at Sage Day. I am proud of the Sage Day Lower and Middle School students, families and faculty for creating and maintaining a culture that is warm, encouraging, challenging and healing both in the classroom and throughout the clinical experience.
