During World War Two, Rabinovich's father escaped the Nazis and fled with his entire family to the land of Israel (then Mandatory Palestine).

Following five years at Telshe, Rabinovich moved to Beis Medrash Elyon, a yeshiva for advanced learning in Spring Valley, New York.

Rabinovich married Nechama Perl, daughter of Rabbi Aron Bernstein of Jerusalem in 1962 and was immediately appointed as leader of the Munkacs community.

He immediately began to rebuild the community and established religious and educational bases in the United States, Canada, Israel, England and Australia.

Rabinovich has authored numerous books on Torah and Halacha (Jewish Law), among them Sharei Orah and Olas Shabbos.
