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.

Xavier is a Mathematical Artist who researches psychological dynamics and expression. He aims to foster balance through thoughtful, holistic, and positive interactions. In pursuit of balance, Xavier has a formal education from Vanderbilt University with a degree in systems thinking and cybernetics (“AI”). Xavier has experience working with some of the most respected names in college test prep, drawing from time-tested techniques for mastering the math and verbal sections of the SAT and ACT.  He currently advises an education startup in India with a focus on helping dedicated students interested in mathematics to be competitive in college applications, to start their own high school math clubs, and to enhance their joy of all levels of math up to college. Personally, he has pioneered a form of thinking called “Thinking OMNI” that aims to make it easier for people to blend their knowledge and rapidly discover new insights. What can dance teach us about medicine? What can medicine teach us about mathematics? Thinking OMNI in this manner has allowed Xavier and the organizations he has worked with to be at once expressive and productive in industry, academia, and our communities. He has also performed nationally as a singer and vocal percussionist with his a cappella group, the Vanderbilt Melodores, and performed poetically as a spoken word artist and orator. Xavier believes that a well-rounded student is one who is prepared for the world both as it is today as well as how it will be. Through adaptation with a respect for wisdom, we can each creatively express ourselves while pursuing greatness in a changing landscape.
