Tim Sanders has a life-long passion for education. Not only does he hold graduate degrees from three universities, but he spends all his time teaching for Manhattan Prep and all the rest of his time organizing math competitions for school-aged children.

Tim started his career as a high school math teacher in Kansas City before completing two graduate degrees in education and then moving on to law school. Naturally. Of course, lawyers don’t get to experience the pure joy that comes from helping a class full of students understand a challenging concept, so he jumped at the chance to join Manhattan Prep shortly after graduating from law school, baffling everyone in the Career Services office at Stanford except those who actually knew him. Tim’s anti-drug is the high-stakes test, preferably taken in regular doses and purely recreationally. He got a 1510 on the SAT back when that meant something, two 800s on the GRE Analytical Reasoning section when that was still a thing, a 177 on the LSAT, and a 780 on the GMAT. Oh yeah, and he passed the California and Texas bar exams. Just for fun, of course. One of the few things Tim enjoys more than taking these tests is teaching students how to take them. At Manhattan Prep, Tim has taught in-person classes in half a dozen cities and has extensive experience teaching online classes. You can read his posts on the MPrep forums and hear his voice on many of the GMAT Navigator video explanations. He regularly works on curriculum development projects and provides support to students through office hours and post-exam assessment programs.

When he gets a few hours’ break from teaching for Manhattan Prep, Tim spends his time organizing math contests for students in grades 3-12. His brainchild, mathleague.org, runs the state math championships for elementary and high school students in several states. Tim’s idea of a vacation is taking this show on the road, training teachers and organizing math contests in random foreign countries.
