The Roslyn Synagogue has a tradition of participating in the education of the next generation of modern orthodox rabbis. The Roslyn Synagogue and Rabbi Block annually host a rabbinical intern. The rabbinical intern, at regular intervals, provides sermons and educational activities to the Roslyn Synagogue congregation, while getting real life rabbinical experience.


Originally from Fairfax, VA, Yosef Postelnek now lives in Teaneck, NJ, with his wife Aliza. Currently in his third year of Semicha in YU, Yosef is also an assistant rebbe for YU’s Beis Midrash Program and previously taught Mishmar to 11th grade boys in MTA. Aliza is finishing her masters degree in Jewish education from Azrieli while also teaching Chumash and Navi to 7th and 8th grade girls in RYNJ. Both Yosef and Aliza have a passion for teaching and connecting with others and are very excited to join the Roslyn Synagogue this year. They are looking forward to a year full of excitement, learning, and growth!
