Who is Bill?

I am taking a sabbatical year, and I will work as an online tutor for the right clients during that time, most likely working with a select few International Baccalaureate and Advanced Placement Calculus students, but I am open to what the universe presents.

I have taught high school and middle school mathematics for 31 years in ten schools in five countries. I love mathematics, and I love sharing that passion with others of all ages and abilities.

I have tutored throughout my career, and I used the Covid pandemic as an opportunity to learn how to connect with my students and help them learn math via video chatting and shared whiteboards.

For five years, I was a Deputy Chief Examiner for IB Mathematics SL, writing and leading the assessment of exam papers during that time. 

President Barack Obama recognized me with the 2013 Presidential Award for Excellence in Mathematics and Science Teaching. I spent the award’s $10,000 on a racing bike.
