Sheri studied Political Science and Information Systems while in college. After graduating, he worked in IT for a number of years and has always been a secret "fan" of Math. Sheri is the kind of person who enjoys puzzles, mental challenges, and explaining numbers and technology concepts to people and did so in various volunteer roles. Sheri also wanted to work part-time for a while and Mathnasium was and is a great fit. Favorite Number: "2000 because Y2K was supposed to crash all the computers in the world, but in reality, nothing really happened! (We were lucky)." Favorite Math Joke: "Three statisticians are practicing their archery skills by firing arrows at a target. One shoots and misses two feet to the left. The second shoots and misses two feet to the right. The third one jumps up and says 'Yay – We got it!'"
