Laurel Hill staff members are highly dedicated, experienced professionals committed to teaching through the magic of play and fostering community through strong home-school connections.


Maria Chew - Director

Director Maria Chew has been an educator and an advocate for children and families for over 20 years. Starting her career as an elementary school teacher, reading specialist, and public school advocate, Maria’s educational philosophy came full circle when her son came to Laurel Hill in 2001. Discovering the impact that a strong, supportive community had on her own family, Maria quickly recognized that a co-op provides a strong foundation for child development and growth; not only for a child’s future education but for that child’s entire life.

Along with supervising staff and advocating inside the school and out for the LHNS educational philosophy, Maria has served as a preschool teacher in Red Room and a Pre-K teacher in Purple Room, and enjoys working with our dedicated community of educators.

When she isn’t attending Tuesday night meetings you can usually find her spending time with her husband Brian, her sons Dexter and Oliver, and her very large extended family.

Marissa Andrade - Teacher

Marissa Andrade’s love for teaching began in 2009 when she became an instructor at an enrichment studio in her hometown of Los Angeles. There she was blessed to experience working with both parents and children instructing a music and movement program dedicated to teaching young children through play. While working there she received her Bachelor of Science degree in Child Development from California State University, Dominguez Hills. After graduating she made the move to San Francisco where she began nannying for a couple of families. She then decided it was time to commit to a teaching position. After a year at another school, she heard about a position available at Laurel Hill and knew this is where she wanted to be. Since joining the Laurel Hill staff in 2016, she has quickly become a beloved teacher not only of Yellow Room classes, but of daily Music and Movement in Blue Room.

“I believe that in order to be great at what you do you have to love what you do. I always loved music, but when I was able to share my love of music with the children and parents around me I knew that teaching was the path for me.”
