About William
I am a National Board Certified Mathematics Teacher with 31 years of experience teaching mathematics in public schools, independent schools, and international schools in the United States and abroad. I hold a B.A. in Mathematics and Political Science, magna cum laude, from Williams College, where I also received the Morgan Prize for Achievement and Promise in Teaching.
I have taught in ten schools across five countries, including the International School of Lausanne, Taipei American School, TASIS Switzerland, Green School Bali, and Proctor Academy. At Proctor, an independent boarding school in New Hampshire, I served as Head of the Mathematics Department.
My experience with IB Mathematics extends well beyond teaching. As one of five Deputy Chief Examiners worldwide for IB Standard Level Mathematics, I worked with curriculum and assessment, wrote examination papers, and led international teams of examiners.
In 2013, I received the Presidential Award for Excellence in Mathematics and Science Teaching, one of the highest national honors for K-12 mathematics and science teachers. The award included a trip to Washington, D.C., in 2015, where I met with scientists, policymakers, and President Obama.
I bring extensive experience, professionalism, and genuine enthusiasm for mathematics to every student I work with.

My goal is to open students’ minds to the beauty, elegance, and power of mathematics. My lessons are highly individualized and designed to develop understanding, confidence, and independence, not simply to get through homework.
Before each session, I review the student’s notes, assignments, assessments, or specific questions so that I can prepare specifically for their needs. A typical lesson combines conceptual explanation, guided problem-solving, discussion, and challenging problems that encourage students to make connections between mathematical ideas. I adapt my approach continually, using questions and discussion to identify what a student understands and where further work is needed.
What sets me apart is my 31 years of classroom experience and unusually deep experience with IB and AP assessment. I have taught IB Mathematics and AP Calculus, served for five years as a Deputy Chief Examiner for IB Standard Level Mathematics, writing examination papers and leading international teams of examiners, and spent three years marking AP Calculus examinations.
I specialize in IB Mathematics AA and AI, at both SL and HL, and AP Calculus AB and BC. I work particularly well with students at international and independent schools who want an experienced teacher who can help them develop both mathematical understanding and examination performance.
Students can also contact me by WhatsApp or text outside our regular tutoring hours, and I respond to questions the same day. I also welcome communication with parents and, when useful, with a student’s classroom teacher.

I've known Bill since we were in high school and he has always been a phenomenal math tutor/teacher. This is the second year that he has been virtually tutoring my son in IB AA math standard level and the results are clear. My son is excited about math again, looks forward to their weekly sessions and is once again confident in his math abilities. I couldn't be happier.
I worked with Bill during my senior year of high school, and he was perfect. He taught me AP Calc BC, which my school did not offer, and I got a 5 thanks to his incredible teaching style. It was so apparent that Bill has such an admiration for math, and he is so invested in the work that he does. Our tutoring sessions were engaging and fun, and he is very helpful at explaining things in a way that sticks. I totally recommend him if you are looking for a math tutor!
I’ve known William for as long as I can remember, and I am so glad I do! He has been such an amazing math tutor over the past few years, and probably the best math teacher I’ve had in a long time. Our sessions are always productive and helpful, while still remaining light hearted and engaging. I always feel comfortable sharing my ideas around him, even when I am unsure about the content I am speaking about. If you are looking for a tutor that will help you understand something you never thought you would be able to grasp, definitely consider William!!!
