Please meet our team of highly qualified and motivated administrators.

Meet the Teachers

  • Sonja Einoedter

    Senior Director of Operations

    Sonja has been part of the GSB team since the founding days when she was the only non-teaching staff member. She now oversees an ever growing team in her role as the Senior Director of Operations. Sonja manages all administrative aspects of GSB including facilities management, health, safety, operations, transportation, and HR. 

    Born and raised in Salzburg, Austria, Sonja earned an associate’s degree in international business and a master’s degree in education from the University of Salzburg. She was a French teacher in middle and high schools in Austria, France, and Brooklyn, New York, for 10 years before joining GSB as an administrator in 2015. Sonja is also the proud parent of a GSB middle schooler.

  • Lena Bacan

    Administrative Coordinator

    With a background in German Speech Pathology, Lena found her way to GSB in 2016, after moving to New York City from Hamburg, Germany.

    In addition to scheduling for the entire school, she upholds our strong internship program and maintains our German library.

    She enjoys being part of a great team and the welcoming community here at GSB.

  • Amelie Goldman

    Director of Admissions and Community Liaison

    Amelie’s enthusiasm for the world of sports and exercise led her to the German Sport University in Cologne, where she graduated with a BA in Sports Management and Communications.

    After working for a sport-sponsoring company in media evaluation, interning at a German Bundesliga (football league) soccer team in management and marketing and a Division-1 college sports department in Pennsylvania, she found her way back to school—at GSB.

    Now, supporting GSB’s students and community on their educational journey, she is pleased to have found such a strong, caring community. At GSB for four years, she’s been able to wear many hats, including administrative assistant, sports coordinator, and director of admissions.

  • Mikhail (“Mike”) Kalnitskiy

    Maintenance Technician

    I’ve been working with GSB since the start of 2023, and I’m glad to help take care of the new building. I have professional training and certifications in standpipe/sprinkler systems, fire alarm systems, non-flammable medical gasses, HVAC systems, refrigeration, low PSI oil burners, and overall building maintenance. My previous employment has included being the Maintenance Technician for The Education Alliance as well as a Medical Center. I’m enjoying expanding on my work at GSB.

  • Ashley Padilla

    Administrative Assistant

    I am originally from Charleston, South Carolina where I attended the College of Charleston and earned a bachelor’s of science in sociology with a minor in African American studies. During undergrad, I started tutoring GED students, which I found so rewarding and has grown into something I now love doing! After graduation I fulfilled a lifelong dream and finally moved to New York, where I now call home. I’m just so happy to be here!

    Before joining GSB, I was the lead tutor at a New York public library branch, where I tutored students K-8 with homework or assisted them in finding a book. I’ve always been an avid reader and being part of NYPL was a lovely experience. My dream is to be a librarian one day, and I am planning on going to library school for my master’s in library science in the very near future.

    When not working, you can catch me reading a good book with my very cute cat named Girlfriend, or watching any and all new tv shows and movies! I’m thrilled to be here at GSB.

  • Hendrike Stark

    Director of HR

    Before her work at the German School Brooklyn, Hendrike worked for six years in the legal department and consular sections of the German Consulate General in New York.
    Hendrike holds a BS in business communications and behaviorism and studies psychology at the University in Hagen.
    She is also a certified NGH (National Guild of Hypnotists) Hypnotherapist.
    Hendrike was born and raised in Hannover, Germany. She moved to New York City in 2007 and lives in Brooklyn with her family.


  • Yvonne Thomas

    Administrative Assistant

    Above all, Yvonne Thomas is a people person. Throughout her work life, she has held many roles, primarily in customer service. Prior to starting at GSB in 2020, she managed the front desk at Eastern Athletic – just a few floors up from GSB’s first location! When she’s not at GSB, Yvonne enjoys singing and dancing (well. . .sometimes even while she’s at GSB). She is the frontwoman of her band The Next, which often plays at Sylvana’s in Harlem. She loves being part of the GSB team, and looks forward to greeting students at the door during drop off.

  • Natalie Wilson-Sam

    Health Coordinator

    I am an African American who was born and raised in Grenada, West Indies. As a child, I always wanted to be a teacher, but as I grew older my passion shifted to wanting to become a nurse to care for the sick, regardless of color, race or creed. 

    I graduated from the Grenada School of Nursing in 2006 as a Registered Nurse. In that same year, I started working in the Pediatric Unit at the Grenada Hospital. As my passion continued to grow, I went back to school and graduated in 2010 as a Certified Midwife. 

    In 2016, I migrated to Bermuda where I worked in the hospital’s pediatric unit. In December of 2020, I moved to the U.S. permanently with my husband and kids. Shortly after, I attended Derby University where I obtained my Bachelor’s in Nursing.

    While not at work, I enjoy spending time with family, cooking, and baking.

    I am glad to be able to continue to grow and contribute to the GBS community!

  • Ute Zimmermann

    Director of Development & Communications

    I started my career in programming at the American Academy in Berlin. In 2004 the Academy sent me to New York to lead their US fundraising activities. This was followed by senior fundraising and programming positions at the arts nonprofits Performa and Artadia. Since 2012 I have worked freelance as a graphic designer with a focus on marketing. In this capacity I have been supporting the German School Brooklyn since its founding. I am thrilled to now expand my involvement at GSB and be a part of ushering in this significant next chapter of the school.
