Rabbi Linda Motzkin and Rabbi Jonathan Rubenstein have served since 1986 as co-rabbis of Temple Sinai in Saratoga Springs, New York. They were ordained in June, 1986, at the Hebrew Union College-Jewish Institute of Religion in Cincinnati, and were the first rabbinic couple to share the sole rabbinic position in a synagogue. In addition to their duties at Temple Sinai, Rabbi Motzkin serves part-time as the Jewish Chaplain at Skidmore College, and Rabbi Rubenstein is Pastoral Care Director and Employee Assistance Program Counselor at Four Winds–Saratoga, a private psychiatric hospital.

Rabbi Motzkin is one of a handful of women in the world who is trained as a soferet (a scribe) and is currently writing a Torah scroll, processing deer hides into parchment for the scroll with the help of volunteers. She is also the author of the Reform movement's four-volume adult Hebrew language series: Aleph Isn't Tough, Aleph Isn't Enough, Bet is for B'reishit and Tav is for Torah. In addition, she is co-author of The First Hebrew Primer: The Adult Beginner's Path to Biblical Hebrew and Prayerbook Hebrew the Easy Way, from EKS Publishing.

Rabbi Jonathan is a bread maker and baking teacher who operates a non-profit, charitable bakery, “Slice of Heaven Breads,” out of the Temple Sinai kitchen. "Slice of Heaven Breads" produces a variety of breads and baked goods for individual orders, for special events, and for limited retail distribution, employing community volunteers as well as individuals referred by partnering organizations. Proceeds from the sale of these products support hunger relief programs, Temple Sinai's programs, and other charitable causes. The bakery donates and distributes challah weekly to nursing home residents, hospital patients, and the needy, in addition to donating products for local non-profit fund-raising efforts.

In 2004 Rabbis Motzkin and Rubenstein founded the Bread and Torah Project, through which they offer hands-on programs based on their scribal arts and bakery activities. Together they have given Bread and Torah presentations at conferences, colleges and retreats, and worked with church and synagogue education programs (youth and adult), school groups, scout troops, civic organizations, agencies serving adults and youth with disabilities, and facilities for seniors.

Rabbis Motzkin and Rubenstein are active in a number of civic and religious organizations. Rabbi Motzkin is a member of the Ethics Committee at Saratoga Hospital, and is on the steering committee of the Adirondack Religious Coalition for Choice. Rabbi Rubenstein is a member of the Board of Trustees of Saratoga Care–The Saratoga Hospital and Nursing Home. They are volunteer chaplains at Saratoga Hospital, and are members of the Capital District Board of Rabbis and the Rabbinic Cabinet of the United Jewish Communities.

Rabbi Linda grew up in Los Angeles and is a Phi Beta Kappa graduate of the University of California at Berkeley. As a rabbinic student she served congregations in Montana, Mississippi, West Virginia, and Ohio, and was Adjunct Assistant Professor of Judaic Studies at the University of Cincinnati.

Rabbi Jonathan was raised in Minnesota and Connecticut, received his B.A. from Haverford College and earned an M.A. in Jewish Communal Service from Brandeis University. Before entering rabbinical school he worked for B'nai Brith Hillel Foundations, held jobs in social service and counseling agencies, worked as a corporate personnel executive and as a baker.

They are the parents of three children: Rachel (Ruhi) Sophia, Ari Shalom and Shira Bracha.
