Note From Tacher Kelly:

“At Bunker Hill I enjoy working with families and the great teaching staff. The outside areas create inspiring curriculum and motivate me, as a teacher, to explore learning in our natural environment. At Bunker Hill the home/school bond is strong and valued and working with families, not just children, makes a huge difference in the quality of education provided. I am proud to be part of such a great community.”

Note from Teacher Vanessa:

“I love being around preschoolers and learning to see the world through their eyes. I believe young children learn through fun, hands-on experiences and hope to bring a nurturing, playful, and exciting element to children’s development through play. I also enjoy supporting other parents and being part of such an enriching community that is a co-op.”

Beau Hamada


Beau began her work with children in High school through her love of sports. Since she was very involved in multiple sports she would volunteer at volleyball and basketball camps for children ages 5-12. This definitely grew her love for working with children. From there, Beau worked as a Nanny for multiple families and expanded her work with children and her education at Sonoma State University where she graduated with a B.A. in Early Childhood Education.


Note from Beau:

“I love working with children because I truly believe being able to watch and influence a child’s growth and development is one of the most gratifying privileges, and helped me realize how rewarding a career in Early Childhood Education could be.”

“Ensuring children are given the proper tools to support their development forges a path for their future endeavors. When we support capable learners and put focus into our youth, we can create a brighter future.”
