Meet The Administration

Rabbi Tavi Koslowe
Head of Lower School

Rabbi Tavi Koslowe (Head of Lower School) joined the Ramaz Lower School/ECC in September 2014. A much loved and inspirational educational leader, Rabbi Koslowe came to us from Yeshivat Noam in Paramus, NJ, where he was Assistant Principal of Judaic Studies in the Middle School. Rabbi Koslowe brings to Ramaz expertise in Torah learning; Judaic and general studies curriculum development; technology integration; staff management; and student programming. At Yeshivat Noam, Rabbi Koslowe collaborated with Early Childhood and Lower School administrators in designing a spiraling general and Judaic studies curriculum of skills, content, and values, for Nursery through 8th grade. Rabbi Koslowe also led the school in advancing its technology integration, analyzing student work and classroom management, and oversaw and supported the growth of the student body from 23 to over 225 students and the faculty from four to over 30 members. His peers, parent body, and students all describe him as being approachable, collaborative, process-oriented, and visionary. Prior to Yeshivat Noam, Rabbi Koslowe was Director of Student Activities and a Judaic Studies Teacher at Yavneh Academy in Paramus, NJ, and Educational Director at Camp Stone in Sugar Grove, PA. He was awarded two educational fellowships (YU LEAD and Academy for Torah Initiatives and Directions), and is a frequent presenter at educational conferences.

Lori Ash
Director of Early Childhood

Lori Ash (Director of Early Childhood) has been in Early Childhood education for over 20 years and started as a classroom teacher. She is lucky enough to have over 200 wonderful children in the program and 40 incredibly talented teachers. She works closely with the teachers to plan their curriculum. It is important for her to know all of the children in the ECC, and she spends a lot of time in the classrooms. She especially enjoys doing science experiments with the children. She graduated from Queens College and received her graduate degree in Early Childhood from Hunter College. Personally, she is the mom of 4 amazing children who keep her very busy when she is away from Ramaz.

Hedva Ofek-Shai
Director of Hebrew Language Curriculum and Faculty Supervision for Judaic Studies

Hedva Ofek-Shai (Director of Hebrew Language Curriculum and Faculty Supervision for Judaic Studies) initially joined Ramaz as an assistant first grade teacher before moving into a teaching position in the Learning Center. Hedva has led the amazing change in our Hebrew program over the last several years. She has designed curriculum, worked with every teacher, and visited every class on a regular basis. She has been tireless in her work. As a member of the ECC and Lower School leadership team, Hedva has been an inspiring colleague, with a refreshing straightforward approach to every situation.

Andrew Leibowitz
Dean of Students, Lower School

Andrew Leibowitz (Dean of Students, Lower School) spends every day completely immersing himself in the lives of students, instilling in them self-confidence, teaching them about chesed and menschlichkeit, and creating for them original programming that celebrates Shabbat and holidays, promotes acts of kindness as part of Tikun Olam, demonstrates love of Israel, and shows respect for the United States. Andrew has the ability to see the good in every child and finds every opportunity to cultivate that good, especially in the context of Jewish values. With his unique personal and teaching style, Andrew’s lessons are life-long, lasting well beyond the years the children are in the Lower School.

An educator for 20 years, Andrew joined Ramaz in 2011. Previously he worked at Magen David Yeshiva High School in Brooklyn. He also was an Assistant Dean of Students at Yeshiva University, liaising between the students and the administration, and dealing with behavioral and psychological issues. Born and raised in North Miami Beach, Florida, Andrew received his Bachelor Degree from Yeshiva University and Master of Education in school psychology from Long Island University. He is currently enrolled in PRIZMAH's YOU Lead, an eight-month leadership development program.
