Rav Tzvis Yeshiva has 350 people, about a third yungerleit. There is no mainstream yeshiva for americans in Eretz Yisroel that takes better care of a bochur then Rav Tzvi. He is so warm personal and caring for each and every bochur, always on top of everyones personal wellbeing. he treats the boys just like a father, and ready to go out of his way to do anything for a bochurs need. there is no pressure from him or from your suroundings, just a happy friendly place where everyone likes.
