Mrs. Devorah Leah Kramer, Director

I am the founder and director of Chabad Girls Academy.

I started the school in 2014 with one student and B”H we are growing beautifully. I had a vision of creating a school with a big heart, where every student that walks through our doors will feel loved, respected and will want to learn and work hard.

We believe in creating leaders of tomorrow, today! We are preparing our young ladies for the real world, where healthy relationships, ahavas Hashem, yiras Hashem, good middos and Derech Eretz are our main focuses.

I have been passionate about and involved in chinuch since I was a little girl. I feel so blessed to work in such a special environment with incredibly talented, dedicated and hard working staff who give their all to ensure the growth of EVERY student.

Dr. Shimon Waronker, Principal

Our mission is to empower learners and inspire leaders to make this a better world. I believe that our girls are the “Barzel” – (Bilhah, Rachel, Zilpah and Leah) – the “Iron” that will shape the destiny of our people. My job is to strengthen all the good that they already have.

I received a Masters degree and Doctorate from Harvard University, was knighted by the French government for outstanding work in education, and have led schools in the U.S. and internationally.

I am so happy to have the opportunity to help our community, here in Crown Heights. I see it as an honor to serve in the Shechuna of the Rebbe.  It is my hope that all of the experiences I’ve had in my life will help Chabad Girls Academy become a shining light of hope and help us come that much closer to bringing Moshiach now.

Mrs. Mushky Pinson, Office Reception

I started working at CGA in 2019 as the Administrative Assistant (Office Reception).

I am from Montreal and have experience working for various Shluchim and mosdos. My days are busy with everything from answering the door, phone and emails, doing office work, organizing events and trips, being there for the girls when needed as well as being the point of contact for emergencies.

Each day is more exciting than the last one!

Mrs Shaina Gourarie, Financial Officer

I have been working in CGA since 2018.

I work in the school financial department and I manage all tuition, bills, and all of the school’s finances.

I really enjoy working in CGA where I see first-hand the amazing love, dedication, and devotion which every single staff member has to each student on a daily basis. 

Mrs Mimi Mark, Finance Administrator

I have been the Finance Administrator for CGA since 2016.

I am a veteran fundraising professional and have worked for many Jewish organizations.

I help CGA with fundraising, Board Development, budget management, and our scholarship program. I also do the behind-the-scenes paperwork to keep our school compliant with the NY State Department of Education.


Ms Chana Gajer

I’ve joined the CGA family in 2019 and I’m looking forward to many more years.

For as long as I can remember I loved working with middle school aged kids.

I went to various camps, led many tween clubs and found my place at CGA. My students are well aware that beyond our classroom I’m there for them in any way.

Mrs Mushky Gershon

I am privileged to be teaching at Chabad Girls Academy since 2018. I teach Chumash.

I love teaching and I love working with this age group! I have been teaching middle school for many years, first in Massachusetts, and then in Brooklyn. I was inspired by my own 6th grade teacher, who’s classes I really enjoyed, to want to teach middle school! 

Mrs Rifkey Isseroff

I started teaching in Chabad Girls Academy in 2019 and love it!

I teach a variety of subjects. We do projects and I design the units to make the knowledge relevant.

I love being a part of the girls academic growth and love helping them find the tools to reach their ultimate potential. 

Mrs Yael Rosenberger

I have been a teacher in Chabad Girls Academy since our school began. I’ve had a passion for education since I was a young girl – leading Shabbos minyanim, being a counselor, teaching preschool and then moving to middle school.

I’ve always enjoyed bringing Yiddishkeit to life by creating visual and hands-on lessons to my students. I love the outdoors and being active and I enjoy cooking healthy meals and being creative.
