Academic Staff

John Bibb, Athletic Director, has a Bachelor of Science Degree in Health and Physical Education from Stillman College in Tuscaloosa, Alabama, where he played collegiate football. He has 11 years of PE instruction and coaching experience at multiple grade levels in the Los Angeles area. To go along with his love for the teaching profession, he has acquired skills as a head varsity high school football coach as well as boys and girls basketball coach at the middle school level. John is a sports enthusiast and spends his leisure time exposing and engaging his two sons, ages 7 and 3, in physical and sports activities.

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.

Janay James, 6th Grade Teacher, graduated Cum Laude from Saint Mary's College with a BS in Psychology, a concentration in Behavioral Neuroscience, a minor in Spanish, and a keen interest in Ethnic Studies. Her current hobbies include reading, writing, doing hair, listening to music, making people laugh, and engaging in intellectual debates and conversations. Something interesting about Janay is that she climbed 5 pyramids in two weeks on a study abroad trip in Mexico. Janay chose Manzanita because of its use of community to facilitate student growth. She believes that an academic foundation built on such strong support teaches students how to navigate the world before them, as opposed to just schooling them on academic content. Students can expect to learn what sparks their curiosity in math and science, how to ask beyond-the-surface questions, and how math and science curricula play into the world we live in today, from both cultural and academic standpoints.
