Faculty & Staff Directory

Chanda is the Chief Development Officer, and brings more than 10 years of nonprofit development experience to Gateway Public Schools. Prior to Gateway, Chanda served as the Development Director at Seven Tepees Youth Program. Chanda earned her B.A. in Mass Communications and Public Relations from Towson University, and M.S. in Holistic Health and Nutrition Education from Hawthorn University. As the child of a military family, Chanda isn’t really from anywhere but claims Baltimore (pronounced Bawl-d-moor) as home. Chanda has lived in San Francisco since 2012; the longest stretch of living in the same place in her entire life. She is the founder #ladyboss, a professional women's meet-up group, dreams of cooking with Chef Yotam Ottelenghi, and loves a good spin class.

Ms. Sabine Louis was born and raised in New York. She received her undergraduate degree in Economics and Math from Columbia University and worked as a consultant in the Washington, D.C. area upon graduation. After two years of consulting work, she realized her true passion was education and moved to New Jersey to become a teacher. Ms. Louis loves learning about how people think and learn, and in 2016 returned to Columbia for graduate studies in Cognitive Psychology. In 2020 she made another major shift and pursued her lifelong dream of moving to the West Coast. She has taught in Oakland Unified School District for the last two years and is really excited about joining the Gateway community. Ms. Louis loves living in the Bay Area and all the access it has to outdoor activities. Outside of the classroom she enjoys trail running, practicing yoga and reading.

Aaron will be a student teaching in Mr. Heasman’s classroom this year. Aaron thoroughly enjoyed his time observing and substituting throughout the ‘21-’22 school year, and is excited to be getting more involved at Gateway. The son of two public school teachers, Aaron was infused early on with a love for the outdoors (camping with his family all summer was the norm), history, and education.  

Aaron graduated from Stanford in ‘05 with a degree in Philosophy, and is currently enrolled in the teacher credentialing program at San Francisco State. Since graduation from Stanford, Aaron has enjoyed jobs in the restaurant and outdoor industry, and has spent time living in Tennessee, Texas and Southern California, though San Francisco is definitely where he considers “home” to be. If you ever want to talk about anything backpacking, restaurant, or Argentine soccer related, Aaron is your guy.

Jenna has a Bachelors in Community Studies from UCSC and a Masters in Counseling Psychology from USF. She is a lifelong Bay Area resident who grew up in the peninsula and has been in San Francisco since 2010. She has worked with youth in various roles and environments including as a writing coach and mentor, a music instructor, a substitute teacher, an after-school program teacher, and in community settings while organizing youth-focused music and arts events. As the College and Career Counselor she works on things like flex blocks and enrichment flex opportunities, student opportunities, community partnerships, and school-wide college and career workshops, events and supports. For fun she likes to play guitar and sing in punk and indie bands, read, walk her dog and enjoy the city :).
