Jadelyn San Juan

General Manager

Jadelyn earned her Bachelor of Science in Molecular, Cell, and Developmental Biology from UC Santa Cruz. With a strong academic background in both math and science, she developed an early appreciation for how mastery of foundational skills builds confidence in tackling abstract and complex ideas.

As General Manager, Jadelyn is passionate about helping students experience the same cycle of growth she enjoyed: understanding, confidence, application, and retention. She finds great reward in supporting students through challenges and guiding them to recognize their potential in math.
