About our founder
From learner
to mentor.
Minjun first joined Light and Salt Academy as an elementary school student in its reading program. He received a reading-achievement medal in 2019. On December 14, 2021, he returned as a volunteer through LAS’s Book Club program, teaching English and mathematics to three second-grade students.
He continued teaching many of the same children year after year, adapting lessons as they progressed through elementary school. Beginning in ninth grade, he focused his tutoring on mathematics, helping students develop logical reasoning, analytical thinking, and creative problem-solving. In May 2024, he founded MathBeyond to give younger learners more opportunities to explore challenging problems and develop confidence in their abilities.
In recognition of his community service, Minjun received the President’s Volunteer Service Award in 2023.
Our commitment
Our high school volunteers tutor younger LAS students each week.
Each tutor works with three learners.
We value preparation, patience, and the willingness to learn alongside the students we serve.
