  • Amanda Adelman

    Amanda, a native of Santa Cruz, CA, developed a deep love for the natural environment and native plants. Her exploration of the outdoors fueled her passion for sustainability, leading her to pursue a B.S. in Environmental Management and Protection with a focus on Botany from California Polytechnic State University in San Luis Obispo.

    After working as an environmental educator and Geographic Information Systems (GIS) analyst, Amanda pivoted to early childhood education while working with young children at the Botanical Garden in San Luis Obispo. She brings four years of experience teaching in diverse preschool settings, including Montessori, Reggio Emilia, and place-based nature schools.

    While working for two years in Golden Gate Park at Woodland School and WildChild Forest School, Amanda became deeply connected to the local environmental education community. Most recently, she spent a year in Idaho’s Teton Valley, working at an outdoor science school, exploring the mountains, and deepening her practice of place-based education.

  • Alexander Agosta

    Alex was born and raised in Palo Alto, California. He studied Religion at University of Hawai'i before pursuing his teaching credential in play-based early childhood education at De Anza College where he gained hands-on experience as a student-teacher in a play-based preschool setting. There, Alex developed skills in observation, guidance, and creating a welcoming environment and engaging activities.

    Alongside his work in education, Alex also spent a total of a year living on and off at a Green Gulch Zen Center, where his meditation practice and communal style of living cultivated patience, presence and emotional awareness. He draws from this practice in his teaching in creating a calm, respectful, compassionate environment where young children feel, understood, encouraged, and safe to explore their curiosities and be themselves.

    Outside of work he can be found juggling, practicing gymnastics, experimenting in the kitchen cooking or learning a new language. He enjoys the process of being a beginner and discovering something new.


  • Pearl Baskett-Stone

    Pearl was born and raised in San Francisco, with Golden Gate Park being a very special part of her childhood and ongoing life. She has always had a deep curiosity and love for nature, animals, and children that continues to grow. She is currently enrolled in Early Childhood Development courses to further her education in this wonderful field. Pearl's interest in working with children really blossomed after the birth of her niece and nephew, now ages 6 and 3. She’s had the great pleasure of being a big part in their lives and watching them grow, while also learning a lot from them. With her love for children and nature, she was very drawn to the Little Earthlings program. In addition, she recently dove into the world of biology and completed a Marine Biology and Plant Biology course that ignited her passion for learning about all things related to the earth.
