Rabbi Benzion Klatzko


The conceptual founder of Shabbat.com, Rabbi Klatzko brings over two decades of visionary leadership, staunch support of Israel, and Jewish activism to the project.

A native of Cleveland, Ohio, Rabbi Klatzko received his rabbinic ordination from the prestigious Mir Yeshiva in Brooklyn, New York. At the Mir, he was known for his exceptional diligence in his studies and sterling character traits- both of which garnered him the respect and admiration of the famed Dean of the Yeshiva, the world-famous sage, Rabbi Shmuel Berenbaum, ZTL. After completing his studies, Rabbi Klatzko accepted an offer to serve as Rabbi of the historic Agudath Israel synagogue of Brooklyn, New York. After seven years of galvanizing the community towards greater levels of Jewish living and expression, he began a three year stint as the Rabbi of a distinguished congregation in Perth Amboy, New Jersey.

In what at the time was perceived as a bold move, 1999 saw the Klatzko family move to California so that he could accept the position of Campus Rabbi at UCLA. As a hands-on and loveable ambassador for the Jewish faith, he reconnected literally thousands of young Jewish men and women to their heritage. He also made an impressive splash in the broader Jewish community, earning the moniker “The Hollywood Rabbi.” Some of Hollywood’s biggest stars and producers,including cast and staff from Friends Malcolm in the Middle, Third Rock From the Sun, and Directors and Vice Presidents of Sony, Disney, and Warner Brothers, became regulars at his popular monthly class on Jewish thought.

Beyond transforming lives at UCLA, Rabbi Klatzko’s activities touched-off a revolution that profoundly changed the landscape of North American Jewry. Almost overnight, dozens of young rabbis throughout the country moved their families to campuses with high Jewish populations in an effort to reach out to the unaffiliated and curious. To this day, hundreds of young rabbis seek out Rabbi Klatzko's sagacious advice in an effort to glean some of his wisdom and experience. He currently serves as a National Director of College Outreach and in that capacity oversees and promotes Jewish education and continuity throughout North America. He also serves as an Adjunct Professor at Yeshiva University and lectures at over 50 different North American colleges and universities each year.

A person of indefatigable energy, Rabbi Klatzko is also a successful author, cantor, music producer, and Mohel. A noted Judaica art collector, Rabbi Klatzko is the founder of Simcha Art Gallery in Monsey, New York. His eclectic accomplishments have even earned him the admiration of the United States Congress, where he was honored during a live session of House of Representatives as a “distinguished gentleman making a difference to his community.”

Rabbi Klatzko and his family currently live in Monsey, New York, where hosting 50 or more people for Shabbos in the norm. He has been at the frontier of improving Jewish communal life in the United States for over two decades and is an invaluable addition to the Shabbat.com team.

Lavi Needleman

Lavi Needleman, a Monsey, N.Y. businessman, heard of Rabbi Benzion Klatzko’s visionary dream and was inspired to assist him in getting this unique website off the ground and running! Lavi is a Tree Surgeon & Landscape Designer by day, and in his free time, he continues the innovative educational methods that he started implementing in Israel 20 years ago.

After attending Yeshiva University, Lavi spent two years in Israel involved in forming an innovative pilot program at Ohr Someach Israel. This afternoon learning program paired up religious, but not motivated students with Baalei Teshuva who were weak in textual skills but brimming with enthusiasm, thus creating a win/win situation both for those being tutored and for those doing the tutoring.

After returning to the U.S., Lavi learned in Yeshivas Mir in Brooklyn and developed a close relationship with Rav Avigdor Miller who lived right next door. In 1995, he and his wife Peshie were members of the kollel in Boca Raton which was the community's successful tryout of a fulltime Kollel. Always looking for unique ways to make a difference, Lavi joined the staff at Camp Moodis where he bonded with and influenced amazing personalities from NASA and other high visibility professionals who were looking for higher meaning in life.

Three years ago Lavi became one of the original Monsey Partners in Project Inspire. In conjunction with this, Lavi’s out of the box thinking and entrepreneurial spirit led him to develop his own motivational e-group as well as a website which provides people short one page original essays that he authored on major important topics, especially in the field of science and Judaism.

Seeing a great void of healthy alternatives, (other than the current baseball and basketball groups) for the religious children in Rockland County, Lavi joined with Rabbi Yehudah Koblick, a co-founder and software developer for this website, and together, they created Yeshiva Hockey Inc, one of the largest sports programs in Monsey where the boys start off each clinic with a Dvar Torah from Coach Yehudah!

To round out his interests, Lavi is a devoted husband and father of five, an accomplished ice hockey player, and the self appointed president of the PAPWESBTTIC (People Against People Who Eat Sushi Because They Think It’s Cool). When not in the office designing landscapes, he can be found hundreds of feet up in the air as he rappels down the Adirondack Mountains, aiming to keep himself both focused and fit. However, the real brick & mortar of Lavi’s day is the nightly class he attends and gives in Jewish Law at Yeshivas Ohr Reuven.

Lavi hopes you find this website inspirational as well as useful tool for Jews the world over, to connect!
