Rabbi Avraham Chaim Bloomenstiel studied in many of Israel’s preeminent academies of Torah study. He received his ordinations as a rabbi and dayan (adjudicator) from HaRav HaGaon Moshe Halberstam ztz’l (Eidah HaCharedis), Rav Zalman Nechemya Goldberg (former chief justice of the Rabbinical High Court of Jerusalem), Rav Meir Sirota (Eidah HaCharedis) and Rav Dan Channen (moreh hora’ah of Ramat Beit Shemesh).
He was certified as a shochet (kosher slaughterer) by HaRav HaGaon Nesanel Kostelitz and Rabbi Yechezkel Feit (Rosh HaShochtim of Empire Poultry). Rabbi Bloomenstiel learned safrus (scribal practice) in Israel and the United States. His ordinations and certifications as a scribe came from Rav Avraham Tzvi Wosner (Rav of Satmar, Monsey, NY), Rav Moshe Halberstam ztz’l (Eidah HaCharedis), and Rav Dovid Leib Greenfeld (Vaad Mishmeres Stam International). Rabbi Bloomenstiel is recognized as one of the United States’ leading experts on scribal laws, traditions, and practices. He is also the author of the Maayanos HaKesuvim, a multi-volume commentary on the laws of safrus, shechita, milah, and other sections of Shulchan Aruch, and is a contributing author on Jewish topics and religion for the Encyclopedia of Psychology and Religion. Most recently he authored an appendix on the laws of conversion for the book B’nei Avraham Ahuvecha: Gerim in Chassidic Thought.
