English (6), History (6), Global Stuidies (6th Grade Elective Wheel, Ethnic Studies (E)

Bio: Mr. Ochoa is a lifelong learner with an almost insatiable curiosity. After earning his undergraduate degree in Political Science and Sociology, he decided to continue his educational interests by pursuing a masters degree, while simultaneously working as an instructional aid at a local elementary school and graduate assistant at the University. During his time at California State University, Fullerton, Mr. Ochoa assisted the department chair with research, led seminar classes, and was awarded an honor for his written work in political philosophy. He took some time away from school to travel and explore potential career paths before deciding to apply for the LA Unified District Intern Program, where he subsequently earned his multiple subject teaching credential. Over the course of his career, Bill has taught gifted students in a variety of academic settings, served as a GATE Coordinator and English department chair. He is a fierce advocate for student mental health and believes all children can accomplish great things when given the opportunity to try. A typical day in Mr. Ochoa’s classroom might include a character autopsy, kinesthetic debate, collaborative exercises, brain teasers, and the (not quite so) occasional Star Wars or other nerd-culture reference. He has not quite given up his love for Legos or Star Wars, nor his love for basketball and music; he hopes to pass at least one of these on to his sons, Ezra (3) and Elias (<1). When not working, Mr. Ochoa enjoys exercising, reading, listening to music or podcasts, binge watching the MCU with his wife and building forts with Ez and Eli. He would best describe himself as an idealist without illusions. He brings with him years of experience working with diverse student populations and hopes to have a positive, lasting impact on the GALA community.

Bio: Mrs. Roque-Ferrel is from the San Fernando Valley. Growing up she was very active in sports, playing basketball, volleyball, and competing in track in high school. She has worked with youth since she was 16 years old, as a youth leader and later as a Girls Basketball Coach. In 2012, she was hired by Lisa Leslie to coach for the Lisa Leslie Basketball and Leadership Academy in West Los Angeles. She is also trained as a volleyball and basketball referee. She graduated from Cal State Northridge in 2017 with her Bachelor of Science degree in Kinesiology with a focus on Sports Studies. Basketball helped her to develop team building and coaching skills that would support her transition into teaching in 2017. She taught middle school physical education and continued to coach for 6 years in Northeast Los Angeles. In 2021, she received the Teacher of the Year award. She believes that sports and fitness teach life skills and has let that belief guide her through her mentoring of student-athletes. In her free time, she enjoys watching sports, hanging out with family and friends, and going to concerts. Mrs. Roque-Ferrel is very excited to join the GALA team and help her students learn the skills to develop an enjoyable, active lifestyle.

Architecture Design, Engineering Dynamics, Exploring Architectural Design and Engineering (Middle School)


Education: Bachelors of Science, Biology, SUNY Albany
Masters of Architecture, Southern California Institute of Architecture


Bio: I moved from the East Coast to Los Angeles to study architecture and have been smitten with both the field of architecture and the city of Los Angeles ever since. I love LA’s diversity, its eccentricities and, of course, its weather. I also love the wide range of architectural styles that coexist within the city. In the twenty years that I have been working in the field of architecture I have had the opportunity to work with several amazing architects that have helped to shape Los Angeles, including Frank Gehry, Barbara Bestor and Brenda Levin, and have had the chance to work on projects including Blackbirds, Silvertop and Dodgers Stadium. I love the field of architecture and its balance between art and science, abstract and concrete, drawings and the built environment, and am very excited to share it with the students of GALA.
