@Reb Eliezer
Nowhere in the article does it say that he was raised Yeshivish. His parents only recently made aliyah from the Ukraine. They may have sent him to a kiruv school as a child in the Ukraine but that doesn’t constitute a Yeshivish upbringing. The kiruv apparatus in the FSU should be doing a much better job researching the backgrounds of the children they take into their mosdos.
