As early as 1993, Rabbi Kenneth Brander, then rabbi of the Boca Raton Synagogue, held discussions with the communal leadership of South Palm Beach County about the creation of the first yeshiva high school between North Miami Beach and Atlanta.

In 1996, he organized The Committee to Form a Yeshiva High School, and in 1997 it hired Rabbi Perry Tirschwell as its Head of School to create the school. Mrs. Ora Lee Kanner, who joined Rabbi Tirschwell before it opened, rose from Director of Judaic Studies to Assistant Principal to finally Principal, in 2008.

Mrs. Pam Turk, who was involved in the school from the beginning, was the school's founding president. The school opened its doors to forty-one 9th and 10th graders in September 1998, and has grown quickly in its short history. The school graduated its first class in June 2001. The school was named in loving memory of Jack and Bessie Weinbaum in 2003. The school was originally located in the Jacobs and Rubin Youth and Senior Center of the Boca Raton Synagogue in suburban, central Boca Raton. The center is named for Dr. Merv and Elaine Jacobs and Mr. Lenny and Sima Rubin who both were part of the founders of the Boca Raton Synagogue and instrumental in the early years of its existence. In the summer of 2004, the school more than doubled its space, and Dr. Sam Lasko assumed the presidency of the school. In 2010, Mr. Jeff Harris assumed the presidency.

In June 2012, Rabbi Tirschwell stepped down after 15 years at the helm of the school. Executive Director Shimmie Kaminetsky and Principal Mrs. Ora Lee Kanner oversaw operations at the school during the 2012–2013 transition year, as the school was in the midst of a search process for a new Head of School, which began in 2013. On February 20, 2013, the Board of Trustees announced that it had selected S.A.R. Associate Principal Rabbi Jonathan Kroll as Head of School. The announcement came after a rigorous vetting process undertaken by the newly formed search committee.

In 2015, the school was renamed Yeshiva High School, and construction began on its new campus at the Jewish Federation of South Palm Beach County. It was later renamed Katz Yeshiva High School. The school officially opened at its new campus and building in August 2017.
