Sarah Groark


Sarah is very excited to be joining Compass as the school psychologist. Sarah has been engaged in progressive education for over twenty years. She received her B.A. and an M.A. from interdisciplinary studies programs (The Evergreen State College and NYU). Sarah began her career in education as a literacy tutor at the Children's Workshop in the East Village and was introduced to the Bank Street model. She then worked as an assistant teacher and paraprofessional at several special needs elementary schools while also teaching cooking classes with children for many years at the 92nd St Y. After a decade in the classroom, Sarah realized that her introverted personality was not best suited for the classroom, and she found that the role of the school psychologist was an ideal fit. After completing her M.S.Ed at Brooklyn College, Sarah worked in Maryland and Colorado as a school psychologist in public schools. 

While in Colorado, she decided to indulge her love of learning and entered a PhD program in school psychology at the University of Northern Colorado. Through the doctoral program, she had the opportunity to work with new populations and in new settings. In particular, Sarah became very involved with supporting the growing refugee community in Colorado. Last year, she completed an APA clinical child psychology internship with the University of New Mexico Hospital working in outpatient clinic, inpatient, and integrated care settings. Throughout her career and education, Sarah's primary research and clinical focus has been on supporting diverse and vulnerable students be academically and emotionally successful. 

After seven long years away from Brooklyn, she is thrilled to be back in Brooklyn! Besides her position at Compass, Sarah also is an adjunct faculty at Brooklyn College in their School Psychology program. In her free time, she enjoys walking the city with her dog, cooking, and reading.

Sara is delighted to join Compass as a school psychology intern this year. Born and raised in Morocco, she attended multiple education systems as a student, and developed an interest in pedagogy. She became very curious about the child’s mind and development and wondered how to create nurturing and exciting learning environments in an adult focused world.
