Looking for a math tutor who can help your child build confidence, improve grades, prepare for competitions, or achieve top test scores? I have over 10 years of experience helping students succeed at every level, from elementary math through advanced competition mathematics.

I specialize in Pre-Algebra, Algebra I & II, Geometry, SAT/ACT Math, SSAT Math, MATHCOUNTS, AMC 8/10, and other enrichment programs.

As a dedicated tutor, I have consistently earned 5-star ratings and passed a professional background check. My goal is not only to help students improve grades and test scores, but also to develop confidence, curiosity, and a genuine enjoyment of mathematics.

If your child finds math difficult or uninteresting, I can help make it engaging and meaningful. I use real-world examples, problem-solving strategies, and interactive teaching methods to make mathematical concepts easier to understand and remember.

My own academic foundation is strong. As a high school student, I earned a near-perfect Mathematics score on China's highly competitive National College Entrance Examination (Gaokao).

Over the years, I have helped students achieve outstanding results, including MATHCOUNTS state championships, AIME qualification, Chicago Math Competition championships, and MathCON finalist placements. I work with students ranging from those needing extra support in school math to those pursuing advanced competition goals.

The methods I use with my students have also proven successful with my own children. One became a MATHCOUNTS National Finalist, qualified for USAMO, earned perfect scores on the SSAT, ACT, and SAT Math, and was admitted to a top-10 university at age 16.

My younger son became a MATHCOUNTS State Champion and ranked #33 nationally. He earned First Place Individual in the Stanford Math Tournament, achieved perfect scores on the SSAT, SAT, and ACT, earned top scores on AP Calculus and AP Statistics exams, completed a proof-based undergraduate analysis course with an A, and was approved to take 300-level mathem

ACT Math

I have tutored many students in regular school Math and competition Math, such as MATHCOUNTS and AMC. I also help students prepare for SAT Math and SSAT Math. I teach Math in a fun way! As a K-12 Math Tutor, all my ratings are 5-star, and I have passed a background check. If your child is struggling in Math or finds it boring, I can make it interesting for them. Many years ago, as a high school student, I achieved almost perfect scores in a more challenging, Chinese-style SAT Math. For over 10 years, I have tutored elementary, middle, and high school students in various Math subjects, including Pre-Algebra, Algebra 1, Algebra 2, Geometry, MATHCOUNTS, AMC competitions, SAT, SSAT, and more. I have tutored my own children as well. While I respect privacy and don't disclose other students' competition results, I can share my own children's achievements. My first son ranked second in Colorado, became a MATHCOUNTS national finalist, and qualified for the USAMO (United States of America Mathematical Olympiad). He achieved perfect scores in SSAT and SAT Math, which helped him gain acceptance into the best public school in the US and Duke University at the age of 16. Tutoring him in Math was an enjoyable experience. My second child is the state champion of the Oregon MATHCOUNTS competition and a national finalist, with his name listed on MATHCOUNTS' official website. He completed College Calculus 1 and 2 with A grades in 8th grade. Additionally, he scored perfectly in SSAT Math and AP Calculus exams as a middle schooler. In summary, if your child is struggling in Math or wants to learn Math in a fun way to improve their test scores, please let me know your needs. I have a unique tutoring approach that goes beyond what is taught in classrooms. I incorporate real-world examples and games to make Math enjoyable and easy to understand.
