Rosenblum brings more than two decades of professional Jewish communal experience to the position, with executive management expertise in fundraising, Israel and Jewish advocacy, strategic planning and communications.

“I’m eager to get to know the community and build upon the tireless efforts of the lay leadership and professional staff both here at Federation and all of Rockland’s Jewish institutions,” shared Rosenblum.

Steve Gold, Federation board president, thanked outgoing CEO Gary Siepser for his six years of leadership and dedication in Rockland, and 40 years of service with the Jewish Federations of North America.

Gold welcomed Ari to his new role. “Ari has worked both within and outside the Federation system, and we are impressed with his versatility and readiness to take on new challenges,” said Gold. “I’m looking forward to collaborating closely with Ari to build and sustain our diverse Rockland community.”

A native of Toronto, Canada, Rosenblum has served as director of development with the Jewish Federation of Ottawa and Ottawa Jewish Community Foundation; chief operating officer for NCSY Canada, and executive director for the Regional Jewish Communities of Ontario. Since his move to the United States several years ago, he has held executive leadership and development positions with New York-based Chabad House Bowery and Hasbara Fellowships. Rosenblum lives in Riverdale, New York, with his wife and young daughter.

Siepser is assisting with his successor’s onboarding process before retiring.
