Dr. Richard Cuenca, Head of School

Message from the Head of School


For over four decades, the Posnack School has made incredible strides both in serving our children and the broader Jewish community. At our core, the spirit of the Posnack School resides within our students. Every year they actively demonstrate their concern for one another, their care for the school community, and their commitment to making the world a better place. Our school’s original founders believed in a clear purpose that is flourishing today and is as vibrant and alive as ever before in our history.

The Posnack School tradition of offering our students the finest academics AND Judaics within the confines of a Jewish Day school continues every school year. We are proud of our storied 42 year history and the hundreds of alumni who have passed through our doors.

The Posnack School experience is deeply rooted in the traditions of our people and the teachings of our heritage. We strive to instill the values of Torah in our students and bring its lessons alive in a purposeful and meaningful way.

As one of the few kindergarten through 12th grade community Jewish day schools in the United States, our purpose is critical to the overall future vibrancy of the Jewish community. Our graduates walk the campuses of the colleges throughout the world, and their Posnack School training puts them at the forefront of advocating for Jewish causes. Moving beyond college, being a valuable member of the Posnack School family is a connection and partnership that lasts a lifetime and never truly ends. “Once a Posnack School Ram, always a Posnack School Ram” is our motto.

Enjoy going through our new school web site. There is valuable information throughout this site to help you learn more about our school. If you ever need any assistance, please feel free to call our school’s Admissions Office for further information. I look forward to welcoming you to the David Posnack Jewish Day School experience and showing you everything our school has to offer your family.
