Experience it! Explore it!  Enjoy it!

The Jewish Discovery Center is an affiliate of the worldwide Chabad-Lubavitch movement.

Chabad is a Jewish Chassidic movement and a Jewish outreach organization - with over 4,000 branches worldwide - that embraces the millennia-old traditions of Judaism with a welcoming and modern approach.   Chabad's underlying principle is genuine love for and unquestioning acceptance of every Jew.

We believe that Jews are Jews, regardless of affiliation or personal level of observance. We have no "check list" for knowledge, observance, beliefs or lifestyles of the people who attend our programs. Everyone is welcome!

We are founded on the principle that, while Jews embrace many levels of observance in their personal lives, there should be a place for all Jews - no labels and no affiliations - to develop a sense of community, to enhance the experience of being Jewish, to learn and have fun.

We are committed to creating an inclusive community both spiritually and physically. If you or a family member require an accommodation to participate, please let us know 

Our purpose is to uplift, teach, and inspire Jews, to help identify with the beauty and richness of our heritage. There is no commitment involved - just an opportunity to explore and be enriched.

Rabbi & Mrs. Yosef and Rochel Kalmanson, founders of The Jewish Discovery Center, welcome you to join its many programs and services.
