Won Suh

Won Suh

Won’s journey through academia has been an interesting one, to say the least. Having graduated from TJ, Won set out to establish himself as a premier physician. Well, that clearly didn’t happen. But what’s a math major (who decided not to pursue a career in medicine after all) to do? Why, go to law school (obviously, he said, sarcastically). It makes complete and absolute sense, of course, that as a licensed (and active) member of the Virginia Bar, Won pursued teaching instead. Over the years, Won has taught math of varying levels up to AP Calculus BC, AP Computer Science A, language arts (reading comprehension, English grammar, and essay writing), and logical reasoning. Won one day hopes to write a really amazing novel.

One of the best decisions I ever made was to send my son to AoPS Academy for improving his math skills. The results are simply amazing! In addition to dramatically improving his math skills, my son also enjoys the social environment that the academy offers. Personally, I am very impressed with the quality of the entire staff (teaching and non-teaching alike). I would not hesitate to recommend AoPS Academy to any parent who is serious about developing their child's academic potential in a safe and stimulating environment.
