Bio

Hello! I'm a Ph.D. chemist and a certified teacher in both Chemistry and Mathematics, with over 40 years of teaching experience, including 30 years teaching in the United States. My goal is not simply to help students finish their homework, but to help them truly understand the material and become independent learners.

Hello! I'm a Ph.D. chemist and a certified teacher in both Chemistry and Mathematics, with over 40 years of teaching experience, including 30 years teaching in the United States. My goal is not simply to help students finish their homework, but to help them truly understand the material and become independent learners.

My background: I earned my B.S. in Chemistry from National Taiwan Normal University and my Ph.D. in Chemistry from the University of Iowa. I hold high school teaching certificates in Chemistry and Mathematics from Taiwan, and I have passed all California CSET exams in both subjects.

How I teach: I start by finding where each student's gaps are, then break difficult topics into manageable steps. In chemistry, I use 3D molecular models, virtual labs, and animations to make abstract ideas easy to see. In math, I build a strong foundation first, then teach students to approach problems step by step. Because I teach both subjects, students taking chemistry and math can work with one tutor.

Lessons are held at my home in [Arcadia] (students come to me) or online. I am bilingual in English and Mandarin Chinese. I was educated in Taiwan all the way through college before earning my Ph.D. in the United States, so I know firsthand what it is like to learn science in a new language. For students who have recently moved here from Taiwan or China, I can explain difficult concepts in Mandarin when needed, while building the English vocabulary and writing skills they need for class and exams, so they can adjust quickly to American schools. I am also happy to communicate with parents in Chinese.

Approved Subjects

Algebra 1

Algebra 1

As a certified mathematics teacher who has passed all three California CSET Mathematics exams, with decades of experience guiding students through their first algebra course, I know exactly where students tend to get stuck. Algebra I is where many students first struggle with math, and a strong start makes a big difference. I help students master linear equations and inequalities, graphing lines, slope, systems of equations, exponents, polynomials, factoring, and quadratic equations, along with word problems. I teach clear, step-by-step methods and show students how to check their own work. With a solid understanding of Algebra I, students are well prepared for Geometry, Algebra II, and science courses such as chemistry.
Algebra 2

Algebra 2

My mathematics teaching credentials, including passing California's CSET Mathematics I, II, and III exams, combined with my background as a Ph.D. chemist who uses exponential and logarithmic functions every day, help me make Algebra II concrete and meaningful. Algebra II builds on Algebra I and introduces many new types of functions. I help students with quadratic, polynomial, rational, radical, exponential, and logarithmic functions, as well as complex numbers, systems of equations, sequences and series, and function transformations. I focus on understanding how each type of function behaves and how its graph and equation are connected. This deeper understanding helps students succeed in class and prepares them for Pre-calculus and Calculus.
Calculus

Calculus

I hold a high school mathematics teaching certificate, have passed all California CSET Mathematics exams, and use calculus throughout my work as a Ph.D. chemist. AP Calculus AB requires both a strong algebra foundation and a clear understanding of new concepts. I cover the full course: limits and continuity, derivatives and their applications, related rates, optimization, integrals, the Fundamental Theorem of Calculus, area and volume, and differential equations. When students struggle, I identify and fix any gaps in their algebra or trigonometry. For the AP exam, I help students practice both multiple-choice and free-response questions, with a focus on clear explanations and correct notation.
Chemistry

Chemistry

AP Chemistry is one of the most demanding AP courses. With a Ph.D. in Chemistry from the University of Iowa and more than four decades of teaching experience, I know both the science and the exam, and I have passed California's CSET Chemistry III and IV exams for high school chemistry teachers. I cover all units of the course, including atomic structure, bonding and intermolecular forces, chemical reactions, kinetics, thermodynamics, equilibrium, acids and bases, and electrochemistry. I break complex topics into manageable steps and use 3D molecular models, virtual labs, and animations to make abstract ideas clear. For the AP exam, I teach students how to approach multiple-choice questions efficiently and how to write complete, well-organized free-response answers. I also offer preparation for the ACS Chemistry Olympiad.
Prealgebra

Prealgebra

I hold a high school mathematics teaching certificate from Taiwan and have passed all three California CSET Mathematics exams (110, 111, and 112). Over my 40-year teaching career, I have seen how much a strong start matters. Pre-Algebra is the foundation for all the math that follows, so gaps here can cause problems for years. I help students master fractions, decimals, percents, ratios and proportions, negative numbers, order of operations, exponents, and introductory equations and expressions. I explain each idea patiently with clear examples and plenty of guided practice, so students understand why the rules work instead of just memorizing steps. My goal is for students to build confidence with numbers and be fully ready for Algebra I.
Precalculus

Precalculus

Because I hold mathematics teaching credentials, have passed California's CSET Mathematics exams, and teach every course from Pre-Algebra through AP Calculus, I know exactly which Precalculus skills students will need next. Precalculus brings together algebra, functions, and trigonometry, and prepares students for calculus. I help students with polynomial, rational, exponential, and logarithmic functions, trigonometry and identities, function transformations and inverses, sequences and series, vectors, and an introduction to limits. I focus on the skills that matter most for calculus, so students are not only ready for their Precalculus tests but also well prepared for AP Calculus.
Trigonometry

Trigonometry

40-Year Math Teacher – Truly Understand Trigonometry. I am a certified mathematics teacher who has passed California's CSET Mathematics exams, and as a scientist I rely on trigonometry myself, so I can show students both the logic behind it and why it matters. Trigonometry introduces many new ideas at once, and students often feel they must memorize everything. I help students understand the unit circle, radian and degree measure, trigonometric functions and their graphs, identities, solving trigonometric equations, inverse functions, and the Laws of Sines and Cosines. Instead of relying on memorization alone, I show students where the formulas come from and how they connect, so they can rebuild them when needed. A strong grasp of trigonometry is essential for Precalculus, Calculus, and physics.

Great lesson

knew his stuff. Helped my daughter my daughter understand the material she was stuck on. She is now ready to take her exam.

Frank, 1 lesson with Gwo

Knowledgeable

I liked that Gwo used the graphs to help explain the Slope Intercept Concepts to my son. He was straight to the point that I could appreciate. I liked that he was able to help both of my children with math and that he would be able to continue to help my children with math all the way through high school.

Great Tutor

My son says he is very patient and explains everything so that he can understands. He even ask us to send him the homework assignments so he can fully be prepared to tutor my son. That is above and beyond!
