Berman was the rabbi of Congregation Beth Israel (Berkeley, California) from 1963 to 1969, of Young Israel of Brookline from 1969 to 1971. In 1971, following his departure from Young Israel of Brookline Berman was appointed Chairman of the Department of Judaic Studies of Stern College for Women of Yeshiva University. Under his leadership over the next thirteen years, it grew into the largest undergraduate Department of Jewish Studies in the United States.[1]
In 1984, he accepted the position as senior rabbi of Lincoln Square Synagogue in Manhattan, New York where he served until 1990.[2] During those years, he spearheaded an expansion of the adult education program, the creation of an extensive social action program based on frum commitments, the growth of the Synagogue's Women's Tefillah Group, and the creation of new outreach programs to the unaffiliated.
In 1990, Berman returned to academic life, as associate professor of Jewish Studies at Stern College, and as an adjunct professor at Columbia University School of Law, where he teaches a seminar in Jewish Law. From 1995 to 1997, he served as Scholar in Residence at the JCC on the Palisades in New Jersey.
