Youngkun Weiss
Director of Operations
Youngkun's journey in education began with his pursuit of a bachelor’s degree in Pure Mathematics at Revelle College, University of California San Diego (UCSD). However, his passion soon shifted towards math education, prompting him to change his major to focus on secondary education. Since 2013, Youngkun has been actively involved in tutoring and various educational initiatives, demonstrating his commitment to education both within and beyond academia.
In January 2015, Youngkun became an instructor at Mathnasium, driven by a desire to make a direct impact on students' mathematical experiences. His dedication and leadership abilities quickly became evident, and by late 2017, he had transitioned to the role of Center Director. His continued success led to his promotion to Director of Operations in early 2023, where he now oversees multiple Mathnasium centers, including those in San Diego, Phoenix, Denver, Dallas, and Cincinnati.
Youngkun firmly believes that every student deserves to approach math with confidence. He is a staunch advocate of the Mathnasium method, which emphasizes a deep understanding of mathematical concepts and aims to eliminate the fear of math that often impedes student progress.
Committed to fostering the personal and professional growth of both instructors and students within his region, Youngkun strives to create an environment where learning math is a positive and empowering experience.
