Meet Your Regional Manager

Hi, I’m Christian Yesa, and I currently serve as a Regional Manager in expanded learning. I earned my Bachelor’s degree in Kinesiology from San Francisco State University, which gave me a strong foundation in child development, health, and physical education. Over the years, I’ve managed more than 20 school sites at once, supporting program quality, building district partnerships, and developing staff to deliver high-quality enrichment opportunities. My passion is creating safe, engaging, and inclusive environments where students can thrive not just academically, but socially and emotionally. What motivates me most is seeing young people grow in confidence, curiosity, and leadership through hands-on, experiential learning.

Meet Your Site Directors

Kelly recently graduated from Santa Clara University with a bachelor’s degree in psychology and sociology. Following graduation, she served as an AmeriCorps member, working as an academic advisor for first generation middle school students. Passionate about education and youth development, Kelly sought new opportunities to support children’s growth and learning. She is now thrilled to join AlphaBest as the new site director for the Portola Valley district and looks forward to building strong connections with students and families as she gets the program started.
