there are dozens of rabbeim tzadikkim similar to reb dovid trenk, whether they work with metzuyanim & their particular challenges or those who need alot of motivation even for the basics .
what is worthy of discussion is that despite the miracles rav trenk performed in the old adelphia days , when he came to lakewood , even with the financial support of so many former talmidim ..sadly his yeshiva couldn’t attract even a minyan of bochurim .the question is WHY? he didnt change “he loved them “. the teretz is , the type of bochur changed the “new weak bochur ” is so much lower than the old weak bochur that attended adelphia , secondly rav trenk zatzl magic worked because it was in the framework of rav shain – the rav trenk menu on its own as a main dish wasn’t sustainable- yehi zichro boruch bgan eden – the solution is way more complex than “just love them”. many of these boys have parents who love them much more than i love my own kids…veheshiv lev avos al bonim
