Mandi Billinge, Executive Director/Founder

Mandi founded KIDS for the BAY and has directed program and organization development for the past thirty years. Mandi was originally a classroom teacher in an inner-city London school. She founded KIDS for the BAY to bring the same exciting, hands-on environmental science projects that she taught in her own classroom into schools in the San Francisco Bay Area. Mandi’s first-hand knowledge of the type of support that teachers and their students need to develop their literacy in environmental science education in the classroom and in the outdoors has ensured that KIDS for the BAY effectively meets the needs of teachers and students and that our programs are very successful. Mandi has a Bachelor of Science Honors Degree in Biology from Hull University, England, specializing in freshwater and estuarine ecology, a Multiple Subject Teaching Credential from Leeds University, England and the Development Director’s Certificate from the University of San Francisco. Mandi loves being a Mom to her three children, and exploring in nature with her family. She also enjoys dancing, swimming, reading and going on hiking adventures.
