Tutors Tackle Tinseltown

When entertainment executive Marc Potash landed a job at Universal Pictures last spring, the offer didn’t come out of the blue. After all, Potash had an inside connection at Universal — not because of his background in film production, but because he had been the bar mitzvah coach of the studio co-chairman’s son.

Potash, 28, is one of a handful of budding entertainment professionals who work with Hebrew Helpers, a Los Angeles-based Hebrew-instruction and bar-mitzvah-training service that culls its staff — and the majority of its clients — from the ranks of show business.
