Rabbi Avremel Okonov, Executive Director

Rabbi Avremel Okonov was born in New York. His father is from Ukraine and his mother from Moscow. He grew up watching his parents devote their lives to helping others. His father, at the Lubavitcher Rebbe’s instruction, was one of the founders of the F.R.E.E. organization, which works to assist Russian-speaking Jews. After receiving his rabbinical degree in Melbourne, Australia, Rabbi Avremel decided to follow in his father’s footsteps, and founded Mazel Day School together with his wife Chani, where he serves as the Executive Director today. Rabbi Avremel has worked with children of all ages for many years, here in our community, as well as in Manchester, Kishinev, Vilna, and more. He has received training from Young Israel Institute for Rabbis, as well as from the Institute of Day School Management at Columbia Business School. He believes and follows the Lubavitcher Rebbe’s vision and philosophy to accept and love every Jew, and inspire and educate them about our great Jewish heritage in a warm and kind environment. The secret to Jewish continuity is rooted in the 3 loves: Love of Hashem, Love of every Jew, and Love of our holy Land of Israel, all of which are tied together through the light of Torah. Rabbi Avremel is part of the team of rabbis at the Hebrew Alliance/F.R.E.E. Synagogue. He lives in Manhattan Beach together with his wife Chani, and children, Mendel, Shifra, Dovid, Mordechai Yisroel, Bluma, Bassie, Yocheved, Shmuel and Mussia.

This experience gives Kate an even greater appreciation for Mazel’s acceptance and respect for Jews of different observance levels. Kate and her husband, Izik Ilyaguyev, passionately support the school’s mission and are proud to have their three children attend Mazel, their oldest joining the inaugural High School class of 2025.

Natalie Zelenko, MD

Natalie’s approach to Judaism and Jewish education rest very soundly upon the tenets of Modern Orthodoxy, placing a profound importance on one’s Jewish life and Jewish values as critical contributions to modern society as a whole. Natalie is a firm believer in the importance of an outstanding secular as well as Jewish education – and the complementary nature of the two. For her own children Natalie has found such an education at Mazel Day School and believes in the importance of MDS in making such education accessible to families with similar goals residing in south Brooklyn. She feels that the warmth and nurturing environment at Mazel are crucial to its educational credo.

Natalie holds an MD from Cornell University Medical College and is the Director of Breast Imaging at NYU Langone Brooklyn. Her practice focuses on breast cancer screening, diagnostic interventional procedures and preparation for surgical treatment options. She is very passionate about advancing clinical breast cancer research, attending numerous conferences throughout each year as both a speaker and a listener.

Natalie lives in Manhattan Beach, Brooklyn, close to Mazel Day School, with her husband Vlad and two children. She is an active participant in the Manhattan Beach Jewish community. In her spare time Natalie loves to travel; when not traveling her favorite leisure pastime stateside is exploring the vibrant art life & culture of NYC and showing it to her children.

Erik Yankelovich

Erik immigrated to the United States with his family in 1990 from the Carpathian part of Ukraine which was devastated by the Holocaust. Erik’s maternal Grandmother is a survivor – one of 8 siblings to make it out alive. She practically saw her parents and brothers and sisters walk into the gas chambers. From his paternal side, both of his grandparents, who were married before the war, were “lucky” to come out of the camps alive and reunite, but without all three of their children. They were able to rebuild their family by having three more kids postwar. Erik is an active member of The Shteible and the Manhattan Beach Jewish Center, where he and his family have found a “home” and have become involved with this Synagogue’s outreach to the Russian Jewish Community as well. Erik attended Sinai Academy High School followed by Stony Brook University where he received a Bachelor of Science Degree in Computer Science. He has been a Commercial Real Estate Broker since 2001 and is a Principal and founding member of Atlas Realty Group Partners (ARG) in NYC.

Maryanna is a devoted wife and mother, an active member of her community, and a trained nurse by profession. Deeply proud of her Jewish heritage, she has always sought to strengthen her connection to Judaism – from her own experience attending yeshiva as a child to ensuring that her children receive a strong Jewish education. Born in Ukraine, she immigrated to the United States at the age of four and has spent most of her life in Brooklyn. In addition to her deep faith and community involvement, as a passionate homemaker, Maryanna finds joy in baking challah, cooking, and traveling with her family.
