Jadelyn San Juan serves as General Manager and brings a strong academic background in science and math to the team. She earned her Bachelor of Science in Molecular, Cell, and Developmental Biology from UC Santa Cruz, where she discovered the value of foundational skills in mastering abstract concepts. Jadelyn views math as a cycle of learning, confidence, application, and retention—and takes joy in helping students find that rhythm.
She finds working with struggling students both a challenge and a privilege, using each moment as a chance to boost their confidence and build lasting understanding. Her goal is to empower and inspire.
Angie Yuan is the Owner and Managing Director of multiple Mathnasium centers across the San Francisco Bay Area and Seattle Area. She began her career in Silicon Valley, consulting for startups on marketing, operations, and funding strategies. Angie holds an MBA in Management Information Systems from SUNY Albany, where she received a full scholarship.
Since opening her first Mathnasium center in 2013, Angie has remained committed to helping students strengthen their skills, confidence, and love of math. Outside of work, she and her husband Paul enjoy raising their three young “mathletes” and supporting local families in achieving academic success.
Angelic has been with Mathnasium since November 2025. She holds a Bachelor’s degree in Sociology from the University of Washington, with minors in Public Policy and Data Science. At Mathnasium, Angelic enjoys discovering what motivates each student and working together to accomplish page goals, while taking time to check in about their week and what they’re looking forward to. Outside of work, she loves playing board games, keeping a well-stocked tea drawer (her current favorite is Jasmine Oolong) and collecting small trinkets like shells, crystals, and fun keychains.
Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.
