    She manages daily operations at the school, including administration, strategic development, fundraising, and admissions.

    After studying law at LMU (Ludwig-Maximilians-Universität) Munich, Germany, Kathrin moved to the United States in 2008.

    Before joining the German School Brooklyn, Kathrin worked in the political department of the German Mission to the United Nations and then at the German Consulate General in New York.

    As head of administration, Sonja is in charge of GSB’s administrative management. She has implemented and administered school management programs and established policies and procedures for operations at GSB, including admissions, transportation, safety, after-school and camps. 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.

  • Gail Livingstone

    Health and Safety Coordinator

    Gail was born in Guyana, the only English-speaking country on the continent of South America. When she was five, she emigrated to New York, where she’s lived for most of her life. She attended Winston-Salem State University, where she earned her BS in Therapeutic Recreation. After moving back to New York she earned her MS in Marriage and Family Therapy at Mercy College.

    She has worked in health care for 17 years, 12 of them in health-care management. She has worked with children, adolescents, adults, and older adults in in-patient and out-patient settings. Her goal as a health professional is to create a warm, compassionate, welcoming environment that fosters trust and overall wellness. As a mother of two, she understands the importance of wellness and how it affects a child’s ability to learn and grow through the various stages of development.

    Gail is excited to have joined the GSB team. To work in an environment that collaborates with parents to encourage students to strive for excellence, not only in the classroom but also in their communities, has been her dream for many years.

  • 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 my 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.

  • Hendrike Stark

    Director of Finances and 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.
