Bob joined us after a long career at one of the nation’s preeminent test prep companies, where he taught, tutored, and wrote curriculum for the SAT, ACT, LSAT, GMAT, and GRE tests. He obtained an MFA in stage directing from Indiana University, Bloomington and came to New York City to pursue a theater career. In New York, Bob used his natural talent for standardized tests, as well as three years of teaching undergraduates, to begin his career in the test prep industry, where he would eventually become the longest-tenured teacher and curriculum developer at his company. While he has loved being in the classroom as well as presenting online lessons to large groups, nothing brings Bob more satisfaction than working 1:1 with individuals who want to turn the obstacle of a standardized test into an opportunity to achieve a great credential. Bob is still recognized as the winner of one of Jeopardy!’s first Tournament of Champions and a veteran of many subsequent invitationals, clips from which are available on Netflix and YouTube; he is eager to show test takers how to employ the same techniques and mindset to succeed in the testing arena. In his spare time, he serves as the New England theater critic for the popular website New York Stage Review.

Steve grew up in Newton, went to Newton North High School, then attended Washington University in St Louis. He has an MS from the Columbia University Graduate School of Journalism and an MAT from Simmons College.

He’s taught at Belmont High School, Newton North High School, and, for the past 15 years, at Wellesley High School. Each year he makes sure he teaches a mix of ages and abilities, from honors seniors to ninth graders just acquainting themselves with the challenges of high school.

As a tutor, he strives for clarity and directness and loves seeing his students gain knowledge that leads to confidence. When not teaching, Steve cherishes the time he spends with his daughter—they particularly like climbing mountains, walking their dog, Nico, and reading good stories out loud.
