Aaron is excited to meet everyone and be part of Congregation Etz Chaim’s proud history.

Jacob Cynamon-Murphy and his wife Rebecca joined Etz Chaim in 2013. All three of their children attend Etz Chaim's religious school. Rebecca grew up next door in Glen Ellyn and Jacob grew up outside of Syracuse, NY. They moved from the Uptown neighborhood of Chicago to Glen Ellyn in 2013 and then settled in Wheaton 3 years later. Jacob has served as a temple vice president and board member and as a member of the Education Committee and Facilities Committee previously.

The coronavirus pandemic had a big impact on how our congregation was able to meet, worship, and build community. Jacob is excited to be leading at a time that we hope will bring both a return to some of our pre-pandemic programming as well as some continued creativity and innovation. Jacob currently works at LinkedIn, so he would love to connect with you.
