Rabbi Greg Hershberg was born in New York City and raised in Orthodox Judaism. He graduated Pace University, Magna Cum Laude and later owned and operated an executive search firm in New York City, specializing in banking and finance. In 1989, he married Bernadette and while on his honeymoon in Israel had a visitation from the Lord that turned his heart to serving God.

In 1992, Rabbi Greg became involved in the Messianic Jewish Movement and was ordained through the International Association of Messianic Congregations and Synagogues (IAMCS). He became the leader of Beth Judah Messianic Congregation. In 2002, the Lord moved Rabbi Greg and his family to Macon, Georgia, to lead Congregation Beth Yeshua.

The ministry went global in 2010 and Congregation Beth Yeshua became Beth Yeshua International (BYI). What was a local storefront congregation became an international ministry/training center in Macon, Georgia, with congregations and schools in India, Kenya, Australia, Germany, Israel, and across America. In addition, Rabbi Greg's messages are live-streamed throughout the world.

Rabbi Greg currently resides in Macon, Georgia, with his wife, Bernadette, and their four children. More about Rabbi Greg can be found in his autobiography, From The Projects To The Palace.
