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 was ordained by the Ziegler School of Rabbinic Studies in May 2014, where he received the Eliezer Slomovic Award in Talmud.

Aviva Tilles was raised in the greater Washington DC area. After graduating high school from the Charles E Smith Jewish Day School during which time she was an active USYer including being a chapter president, Encampment co-chair & going on USY on Wheels and USY Israel Pilgrimage, she spent a gap year in Israel on NATIV - USCJ's college leadership program before heading to Worcester, MA to attend school at Clark University where she earned her Bachelors in Sociology and her Masters in Public Administration.
