  • David Calabrese

    David Anthony Calabrese, Founder & Director

    David grew up in a big family in Wallingford, Connecticut, playing in the surrounding woods and farmland all four seasons.

    As a young parent in New York City, David co-founded the parents group, “Preschool on the Planet.” After moving to San Francisco, his family enrolled in the Rocky Mountain Participation Nursery School, where David became parent education chair. He continued on as Lead Teacher and briefly as Director at Playmates Cooperative Nursery school, before founding Little Earthlings in 2017.

    He has a Master of Arts in Early Childhood Education from San Francisco State University, a Preschool Site Supervisor Certificate from San Francisco City College, and a Bachelor of Fine Arts with Honors (and a secondary in Philosophy) from Manhattanville College in Purchase, New York.

    He is part of a music and film production team called Telling Visions Unlimited, and loves playing music, producing, writing, cooking, eating and most of all his children (both attending UC Davis.) He is also at work on a documentary about San Francisco’s historic Hyde Street Studios & Wally Heider Recording.
