His passion is rooted in his years as a social worker, coming to Ramaz from the SINAI School at Heichal HaTorah in New Jersey, where he worked with children and young adults with special needs to be productive members in their community.

At Ramaz, Jordan is responsible for creating a values-based culture that is inclusive, spirited, and in accordance with the Ramaz mission. Known as a team player, Jordan partners with teachers to create programming that supports and enhances the academic and social-emotional goals of the classroom.

Prior to joining the SINAI school, Jordan built the youth department at Congregation Ohr HaTorah in Bergenfield, New Jersey, on the premise that every child belongs. As its present Youth Director, Jordan works tirelessly to create experiences that highlight the strength and inner beauty of each child and implements programs where children see that they have an impact on their community and the world around them. Youth in his synagogue find themselves participating in myriad activities, ranging from Shabbat morning groups with children of special needs to girls' Motzei Shabbat learning to holiday-themed HQ games. Jordan also worked at the Ohel's Children's Home and Family Services, where he oversaw the operation of community-based programs with over 150 clients and mentored and supervised over 200 staff members.
