As a child, she adored listening to the stories of her Lolo and Lola, both of whom were teachers before they immigrated from the Philippines. Supported by her hardworking family, she learned empowerment through education. After attending both public and private schools around the San Fernando Valley and graduating from Notre Dame High School in Sherman Oaks, her passion for equity and social justice led her to study Ethnic Studies and Education at UCSD. Upon graduating, she jumped right into her first teaching job, while earning her Multiple Subject Teaching Credential at CSUN. During her 23 years as an educator, she has remained passionate about providing her students with an empathetic, empowering, and equitable education. Before GALA, she taught Kindergarten, 2nd, 4th, 5th, and 6th grade. Her past eight years were spent at Melrose Avenue Elementary Math/Science/Technology Magnet in West Hollywood. Ms. Valera brings with her a deep love of reading, writing, and history, as well as a fervent commitment to the implementation of Social Emotional Learning, restorative and trauma-informed practices, anti-racist curriculum, and culturally/linguistically responsive pedagogy. As a mother to an innovative and strong 11-year-old girl, she feels especially honored to be part of GALA's mission of ensuring that young women possess the academic foundation, leadership qualities, growth mindset, and self-confidence to go out and succeed in STEM fields. When not teaching or learning, she loves reading, hiking, and spending time with family, especially her husband, daughter, Abigail, and rambunctious Boston Terrier, Roscoe. One day, she hopes to write a children's book about the adventures of Abigail and Roscoe.

Bio: Hannah Williams was born and raised in the Pacific Palisades, right here in Los Angeles. She grew up dancing at a studio there, alongside performing with her school's theater program. After graduating from Palisades Charter High School, she went on to complete a prestigious dance program at Edge Performing Arts Center, while also receiving her Yoga certification. From there, she began her six year journey as a professional dancer, with opportunities to work alongside incredible choreographers, study many styles, and perform in 15 different countries.
