 Rabbi Howard Tilman

Rabbi Howard Tilman joined Congregation Beth Israel in July 2017 and has enthusiastically embraced this growing community. Through partnerships with professional staff and lay leadership, he has worked to enliven the synagogue’s religious services, educational opportunities, and family programming. Rabbi Tilman loves spending time with the congregation’s many learners of all ages and enjoys bringing modern and classical perspectives, as well as humor, to all of his teachings. Elsewhere in the community, Rabbi Tilman serves as President of the Scotch Plains – Fanwood Ministerium and is an active member of the Union County Board of Rabbis. He is an alum of the Rabbis Without Borders Fellowship and was in the initial class of AIPAC’s Leffel Israel Fellowship.

Rabbi Tilman was ordained by the Ziegler School of Rabbinic Studies in May 2014, where he received the Eliezer Slomovic Award in Talmud. For his Capstone Project in rabbinical school, he analyzed the similarities between the Talmud and modern social media as well as their educational potentials. He previously served as a member of the clergy team of the Jacksonville Jewish Center, where he worked in a variety of roles, including supervising Shabbat and Holiday programming, teen educational programming, and Israel advocacy. While in Jacksonville, Rabbi Tilman became a leader among the clergy of the Jacksonville Coalition for Equality and its push for an expanded Human Rights Ordinance in the city.

Prior to the rabbinate, Rabbi Tilman graduated from Northwestern University with a Bachelor of Arts in Communication and spent three years working as a producer for Sporting News Radio alongside the likes of Troy Aikman, Tony Bruno and Tim Brando. A passionate sports fan his whole life, he appeared on and won an episode of Sports Jeopardy! in August 2016. Rabbi Tilman has extensive experience working with youth of all ages in multiple synagogues and schools and at Camp Ramah in the Poconos. He has also worked with college students and serves as a member of Alpha Epsilon Pi‘s Council of Rabbis.


He is married to Naomi, who serves as an Area Director for BBYO. Together, they are proud parents of Micah and Sophie, who keep everyone busy with their youthful energy.
