Overview - What is the Thursday Evening Celebration?

Thursday, March 2nd, 2017 6:30 pm
Museum of Jewish Heritage
36 Battery Place, New York

For the past decade, Hadar has been a center of Torah learning, a mekom Torah. We have been and continue to be committed to living bolder, more ambitious, and more meaningful Jewish lives through serious study, service, and prayer. As we celebrate our first 10 years, we could think of no better way to recognize this milestone with our community than through a Jewish learning celebration, honoring our outgoing board president Jonathan Lopatin who has been with Hadar since our creation. At the event we will hold a siyyum, a traditional celebration after learning a significant portion of Torah. Whether or not you have joined in the learning, we invite you to join us as we honor Jon for his dedication to Hadar and the Jewish people. This event will include a reception, reflections on our vision, and a keynote address by Rabbi Shai Held on "What Religion Could Be."

ASL interpreters are available at Hadar when requests are made in advance. Please contact [email protected] for more information.
