Art of Problem Solving was founded by Richard Rusczyk in 2003 to create interactive educational opportunities for avid math students. Richard is the author or a co-author of 7 AoPS textbooks and a past Director of the USA Mathematical Talent Search. He was a participant in National MATHCOUNTS, a three-time participant in the Math Olympiad Summer Program, and a USA Mathematical Olympiad winner (1989). He received the World Federation of National Mathematics Competitions Paul Erdös Award in 2014. He graduated from Princeton University in 1993, and worked as a bond trader for D.E. Shaw & Company for four years. AoPS marks Richard's return to his vocation - educating motivated students.

In 2014, Glen founded a learning center in Morrisville, North Carolina, that two years later became the first AoPS Academy campus. Glen served as the National Director of AoPS Academy until his retirement in 2019. He has experience as a college math professor, statistician, and expert SAS programmer. He has been a professional math tutor for many years, and specializes in training academically-advanced and high-performing math students. Glen is a graduate of Duke University and holds a graduate degree in statistics from Boston University.

Hong has taught mathematics at the university level and is a literary translator working between English and Chinese. Raised in a family of educators—his father a history professor, his mother an upper-school principal—he came to teaching as a calling. That background shaped a conviction that mathematical reasoning and clear language are two expressions of the same discipline. AoPS's approach of letting students discover ideas before being told them aligns perfectly with this philosophy. Hong finds particular energy working with students at the age when mathematical intuition is forming, helping them see that a well-constructed proof can be as satisfying as a well-constructed sentence. His classroom is warm, spirited, and demanding in equal measure. He prioritizes the question "why does this work?" before "how do I use it?" and takes student reasoning seriously, even when it diverges from expected paths.

Adam designed and taught his first AP Computer Science class in 10th grade and has been teaching ever since, joining AoPS California Bay Area in 2024. He holds a Bachelor's degree from Tufts University with a double major in Computer Science and Music (classical composition). He is pursuing a Master's in Education at Harvard GSE, focusing on Learning Design, Innovation, and Technology. As a middle and high schooler, Adam studied AoPS textbooks while preparing for math competitions. Now joining as an instructor, he has come full circle. He loves AoPS's philosophy of learning through problem-solving and encouraging students to do the intellectual work. His classes run as continuous dialogue, collaborating through problems and concepts as a community. Expect active discussions and genuine fun.
