Over the past four years, I have given private lessons in Prealgebra, Algebra 1, Algebra 2, Geometry, Trigonometry, Precalculus, Calculus, Formal Logic, Abstract Algebra, Set Theory, Discrete Math, Physics, and Chemistry. Additionally, I was a Supplemental Instruction Leader for Chemistry 40 at the City College of San Francisco.

Feel free to contact me if you have any questions or if you want to schedule a lesson. I'm a very friendly person, and I respond as quickly as possible.

Discrete Math

I have been tutoring discrete math for over 4 years, and I have studied and practiced discrete math for over 6 years. I can help new students with any of the concepts that are taught in the first and second semesters of a college-level discrete math course, and I am particularly interested in teaching students how to write proofs. I can also help students with formal logic, set theory, and abstract algebra.

Excellent, patient, constructive instruction

One of the things that stands out about William is how he corrects mistakes: he tries to understand what the student is thinking, and build from where they are to where the right answer is, rather than just telling them they are wrong

Effective & Efficient Tutor!

William is an AMAZING tutor. I had a very particular request in that my daughter insisted on a tutor who used a stylus to write/draw letters/numbers/diagrams instead of sloppy mouse-drawn characters. William surprised her with his use of a note app, and further followed up the lesson with detailed notes from the lesson. My son also tutored with William and to my surprise agreed to start learning higher-level mathematical theories and concepts from William. William is highly passionate about teaching math, he is articulate and to the point, and made both my children feel at ease. Thank you William for being so patient in answering their endless questions, giving them that extra boost of confidence and instilling a love for math!

Knowledgeable & excellent teacher!

William was patient, knew the material, was engaging and an excellent teacher! My daughter thought he was awesome! He helped her review several chapters for her Geometry test in 3 hours! I highly recommend him!

Fantastic tutor!

My son enjoys his sessions with William so much he has asked to add more! William is patient and kind and figures out very quickly what a student needs and how to tailor the instruction. This has been a great first experience with a tutor!

Great teacher!

Sadly my daughter has a week algebra 2 trig teacher so was looking for a tutor to supplement the instruction. My daughter said that William is an excellent teacher, extremely knowledgeable and explain things easily and even gave her some shortcuts to work through the problems faster. We already have the second lesson set up.

Great teacher, very patient!

He made sure I understood a topic fully before he would continue. I would definitely recommend him to anyone I know who needs a tutor. An excellent tutor for a great price. Thank you for your patience !

Best tutor

Because of him I was able to understand stuff that I never thought I had the brain to understand, he is extremely good, also very funny which makes the lesson enjoyable

Great tutor

My Daughter really enjoyed her first lesson. William did a great job and my daughter, who can be hard to please, was extremely happy with the session. I’m excited to see her progress in Algebra II.
