Sophie Koshland, Junior Kindergarten

For more than ten years, Sophie has taught children of various ages, from preschool to fifth grade. Now in her seventh year teaching Junior Kindergarten at AVS, she continues to be inspired by the infectious enthusiasm and fearless resiliency unique to such young learners. Sophie strives to design explorative curriculum that engages the fun-hearted imagination of her students and sparks their endless curiosity. She believes the classroom environment should be inclusive and empathetic, and learning should be child-centered and hands-on. She especially loves to infuse her passion for science into integrated units. During a favorite study, students visit local redwood forests to inspire wordless storytelling of prehistoric life, and return to find their classroom transformed into an active dinosaur dig. Sophie is grateful to be part of a vibrant community where both teachers and students are continuously challenged to open their minds and hearts.

Susan Garrison, First Grade B

For over 30 years, Susan has dedicated herself to creating engaging, joyful learning experiences. As a student of mindfulness, Susan incorporates the practice into her daily morning meeting to set a tone of peace and kindness that guides our interactions. She has taught grades K-5 at both private and public schools and designed hands-on learning opportunities that challenge children’s thinking and cooperative learning skills. One of her favorite learning experiences is the Science Fair in which students work in pairs on any topic of interest to them, follow their curiosity, and freely explore. Most recently, she taught fifth grade at Blue Oak School in Napa, where she worked for the past eight years. Her classroom expanded beyond the four walls where students learned that math applies everywhere, whether it’s the speed of the river, shadows created by the sun, or the design of a building. She is confident that working with children is what keeps her young. Susan loves living in the Mission District with her husband, Dr. Greg Garrison, who teaches science at the AVS Middle School Campus. They spend their free time camping, sailing, hiking, and traveling across the country.
