I am a professional math tutor, engineer, and entrepreneur who established tutoring business which have been helping more than 2000 students over last 16 years. I graduated from University of Illinois at Urbana-Champaign with Bachelor of Science in electrical engineering. I have been tutoring all level of math from elementary school math to high school math including AP Calculus AB/BC as well as IB math SL/HL. Also, I have been tutoring SAT math and ACT math and science section and many of my students got perfect scores. Before I started my professional tutoring career 16 years ago, I worked for Lucent Technologies as a research engineer for two years, and for TriQuint as a product marketing engineer/manager for 3 years and Korea country manager for two years. Math can be easy and fun subject once students secure good foundation for any math topics, and my tutoring methods are focused on developing rock-solid foundation by identifying and helping the root cause of any weak area. My hobbies are golf, ice skating, skiing, hiking, camping, automobile and air travel, and learning new software language.
