Hi,

I am a STEM educator with over 25 years of teaching experience specializing in advanced Mathematics (AP Calculus AB / BC, AP Statistics) and Science (AP Chemistry, AP Physics 1). and I also have been tutoring standardized tests such as SAT Math, ACT Math/Science, ISEE Math all levels, GRE Math, etc. I hold a Master's degree in Mechanical Engineering from University of Southern California (USC).

I am a best-selling author of over eight STEM textbooks, topped Amazon’s “#1 New Release” charts for AP Precalculus, AP Chemistry, AP Calculus AB, AP Calculus BC, AP Physics 1, Digital SAT Math, Enhanced ACT Math, etc.

With a proven track record of coaching students to top-tier finishes (90% over 750 in SAT Math and 34 in ACT Math/Science), I have also maintained a 95% pass rate (Scores 4 or 5) among my AP students for their AP Physics, AP Chemistry, AP Calculus AB/BC, AP Statistics. I have been helping my students for their weekly tests/quizzes for school math and science subjects as well in order to keep their 'A' grades.
