Josh Berkowitz

AM Nursery Teacher

Josh grew up in Los Angeles but has called San Francisco home for over twenty years. After earning a BFA in Illustration from the Academy of Art, he worked for several years as a graphic designer. When his daughter was born, he decided it was time for a change; he returned to school to study Early Childhood Development at City College, earned his Site Supervisor permit and launched his second career as a preschool teacher. As a teacher, he wants children to experience the joy of discovery, feel comfort in who they are as people and know that what they think matters.

He enjoys taking advantage of the culture the city has to offer with his wife and daughter, going to live music performances, drawing and cycling around the Bay Area.

Carlyn was born and raised in Erie, Pennsylvania before moving west in 2009. She has been in the Bay Area since 2011, receiving both her Child and Adolescent Development undergraduate degree and Early Education Master’s degree from San Francisco State University.

Paul Chinn

PM Nursery teacher

Paul was born and raised in a small town in Kentucky and reflects on that experience as a guide for the importance of relationships and social values. He has a Masters in Early Childhood Education from Bank Street College in New York City, and has followed that progressive, experiential thread through his 25 years in the field. Paul has experience in a variety of programs: migrant childcare in Upstate New York, the first Infant/Toddler program on Long Island, Intergenerational, Corporate-Sponsored, Reggio Inspired, and most recently, the San Francisco Unified School District. His joy in teaching comes from watching children (and adults) express and share their ideas, ask questions that lead to more questions, have “Eureka” moments, and learn to build community. He’s excited to work with the team at One Fifty Parker Avenue School both as a teacher and fellow learner.

For the past eight years Paul, his wife, and their dog Mudpie Grace have called San Francisco home. They enjoy bookstores, Rainbow Grocery, and record shops.

Andrea Hart


Our Director, Andrea Hart, is an experienced early childhood educator and school leader. As of 2016, Andrea serves One Fifty Parker Avenue School as the primary steward of the educational mission and philosophy.

Andrea held the role of founding Preschool Director at the Harker School, a local K to 12 independent school, and the role of Teacher at the Bing Nursery School of Stanford University for over a decade.
