Faculty & Staff Directory

Marcio was born and raised in San Francisco. He attended CCSF and then San Francisco State University, where he earned his undergraduate degree in Kinesiology in 2016. He aspires to improve the relationship that young people develop with physical activity, routine exercise and sports. In his spare time he enjoys anything related to sports and spending time with his family.

Madison is looking forward to starting her position as a Counseling Intern at Gateway this fall semester. She moved to San Francisco from Southern California to study Child Development at San Francisco State University. During this time, she fell in love with the city and all it had to teach her. After graduating, she worked at a small nonprofit middle school in the Outer Richmond area of the city, learning about how to best support students with learning differences. Here, she found her passion for teaching sex-positive health curriculum to students to bring awareness about anatomy, consent, and healthy relationships before or as they begin exploring romantic relationships. Madison continues to modify and add to her curriculum in the hopes of being able to teach more young people about safety and consent in relationships. Madison is currently a 2nd year USF student with a dual emphasis in School Counseling and Professional Clinical Counseling, and is looking forward to working with students at the high school level. In her free time, she enjoys watching movies, eating chips and salsa, and spending time with loved ones.

Mary Plant-Thomas is excited to begin her ninth year at Gateway teaching tenth grade Biology and AP Biology. In addition to teaching, Mary has also served as a Faculty Representative to the Board, the Co-Chair of the Faculty Affairs Committee, has mentored a number of student teachers, and fostered partnerships with UCSF and BABEC. Mary earned her undergraduate degree from an unconventional combination of Wellesley College and UC San Diego. She then went on to get her Masters in Education from UC Santa Barbara's Teacher Education Program where she was able to participate in an international exchange that enabled her to observe another education system by student-teaching in Denmark! More recently, alongside two other Gateway colleagues, Mary was selected to participate in the two-year Hollyhock Fellowship at Stanford University. In addition to loving teaching and biology, Mary has a passion for theatre and can frequently be found rushing off to see plays all around the Bay Area.

She is a Mama-scholar to Ava & Ayson whom she credits to being the best version of herself!

Elena is very excited to transition into a different role at Gateway, and continue supporting Anime Club. She came to San Francisco to pursue a Master’s in Human Rights Education following her Bachelor’s in Ethnic Studies from OSU, and worked a few jobs in SF before coming to Gateway in 2019. Elena loves being involved with La Peña cultural center in Berkeley and supporting social justice causes when and however she can. Outside of school, she enjoys watching other people’s dogs at Duboce, baking (and eating) desserts, making art, and playing video games on her GameCube.

Joel has served as the Director of College Counseling at Gateway High School since the fall of 2005. Since that time, he has continually worked to develop a college counseling program that is responsive to student needs and supports students to make informed decisions in developing their plans after Gateway. Most recently,  Joel and the college team have worked to develop programming that is culturally responsive and supports the social emotional growth of students. In his role as Director of College Counseling, Joel teaches the College Counseling 11 and 12 courses and provides individual college admission and financial aid counseling to students and families. He is also a long-standing  member of the Gateway High Leadership Team and Student Life Team. Joel was born and raised in Richmond, CA and is a child of Mexican immigrants. He believes deeply in the transformative power of a high quality education and educators who advocate for the equitable well-being of their students. Building and easing access to post-secondary education is important to seeking justice for young people from underrepresented backgrounds. He graduated from UC Berkeley with a bachelors in Spanish bilingualism and linguistics and from Stanford University School of Education with a masters in education policy analysis and evaluation. Prior to joining Gateway high, he worked at the Hispanic Scholarship Fund and the Making Waves Education Program. When not working, Joel enjoys hiking through the East Bay hills, riding bikes with his son, and family movie time.

Katy is Gateway High School's Literacy Specialist, working to support students in their growth as readers. She previously taught 11th grade Humanities and AP Literature. Prior to Gateway, Katy taught English and Humanities for 10 years at schools in San Francisco, the East Bay, and Palo Alto, and worked as a director of Breakthrough San Francisco, a program supporting SFUSD students on their path to college. Katy received her B.A. from the University of Virginia with majors in English and Spanish, and an M.A. in Humanities from the University of Chicago. Outside of school, Katy is a parent of three kids, with whom she enjoys reading, riding bikes, building forts, and perfecting boxed mac and cheese.

The stars have aligned! Ariel is joining Gateway’s unbeatable 9th Grade Seminar team. She completed an undergraduate degree at UC Davis that led her to a career as a video producer in the Bay Area - working on commercials for the SF Giants, the Warriors, movies for Netflix…all sorts of things! Unable to shake her passion for working with young people, she transitioned into film education, then health education, then elementary education, finally landing on Gateway’s 9GS team. When she’s not teaching you can find her co-managing a nonprofit for LGBT+ youth, advocating for underrepresented voices at a media justice organization, shooting documentaries, or - her favorite - taking a bubble bath.
