Who can someone go to to get Kaballah in Shechita in America?
Certification for shechitah is known as a "kabalah", not (directly) related to "Jewish mysticism."
I recall seeing a sign advertising lessons that would culminate in an exam/certification from either Rabbi Yisroel Belsky in Brooklyn (who is on OU Kosher's policy panel), or a name in Lakewood I'm afraid I didn't recognize. At least that's one name for you ...
Rabbi Avidan Elkin of Hackensack, NJ
