Organic chemist offering lessons in math, chemistry, and biology in SW Virginia, 20years experience

John was very thorough in his approach. He first tested my child in different ways to understand his math skills. He then made it fun and interesting to learn algebra and then calculus. He is a brilliant mathematician. John is passionate about math. It's actually fun for him to do complicated math problems and explain them. I would highly recommend him to anyone struggling with math at any level. Thank you John!
