Academic Staff

Bob Capune, 7th & 8th Grade History Teacher, has a BA in History from the University of California, Berkeley. Bob worked for two decades at the Lawrence Hall of Science, a hands-on children's museum. Although he likes Science, his true passion is the Humanities. He thoroughly enjoys teaching English and History instead of quadratic equations. An avid world traveler, Mr. C has visited every continent (except Antarctica). He brings photos, stories, and artifacts from these trips to his classroom to share and enhance curriculum.

Debra Hom, 7th & 8th Grade Math Teacher, has a Bachelor's of Science in Mathematics and a Master's in Education from UC Davis. Her hobbies include gardening, cooking, baking, listening to music, making jewelry and crocheting. Debra wanted to work at Manzanita because of the community support and feels the small classes will let her focus on each student's needs to succeed in math. She loves when students ask for help and tell her when they don't understand a topic. Growing up in a small community, she knows that everyone is willing to help and learn together. In her classroom, she strives to make math understandable and relatable to everyday life.
