Demonstrating a comprehensive understanding of Mathematics, teaching for a period of over 4 years,focusing on subjects like arithmetic, algebra, and trigonometry from school to university Level

I can describe William as an excellent communicator and an excellent student in his field. I've known him since university and later from working together right after graduation.
William's background in teaching goes back to his undergrad days when I first got to know him. He would work as a Teaching Assistant in our department as often as his schedule allowed. He was generally a hard-working star student whose reputation would precede him in our university's startup circles.
Discussing any topic with William, technical or otherwise, is always very engaging and effective. I would highly recommend him as a mentor.
