Chaburah Spotlight: Naftali Kieffer

NCSY Kollel August 5, 2025

Naftali Kieffer’s third summer on NCSY Kollel — and first as a madrich — has been absolutely amazing so far. Naftali is from Boca Raton, Florida; he lives where you go to vacation (or visit your grandparents). He is an alumnus of Katz Yeshiva, has just finished two years at Yeshivat HaKotel, and is ready to begin his journey at YU this fall.

Part of what makes Naftali’s Chaburah so unique is the diversity of the guys in it. Starting off with Gavi Engel, who goes to MTA — Gavi always brings his infectious smile, laughter, and chill vibes. Next up, we’ve got the great Aviel “Hey Mann” Kahn from Berman. Aviel’s passion for Talmud Torah and for growth is incredibly inspiring and motivates everyone to want to do better. Yitzi Wiener hails from Yeshivat Mekor Chaim in Maryland. As one of ten siblings, his passionate arguments with Eli during Chaburah are no surprise. Last, but definitely not least, we’ve got Eli Tyszler from the Mesivta of Philadelphia. Eli is one of the sweetest and nicest people you’ll meet and always has something interesting to say.

This summer, Naftali is really excited for his Chaburah titled “What’re We Doing Here?” In it, they are exploring the meaning behind the values of NCSY Kollel — and Judaism as a whole. Topics include “Why We Do Mitzvot,” “Why We Learn Torah,” “What’s the Significance of Eretz Yisrael?” and “What Is the Role of Fun in Judaism?” Naftali is using the Maharal’s Tiferet Yisrael to address many of these questions and hopes the material is engaging and impactful.

The Chaburah has been going great so far, and they’re headed toward an incredible rest of the summer!
