I exclusively tutor the GMAT.

I've worked as a professional tutor for over 20 years. In GMAT alone, I've worked with over 1000 students and have more than 4000 classroom hours. I taught the official GMAT class at Boston Consulting Group, and I've taught professionally at Duke, MIT, Harvard, & Wellesley.

I'm an ex-Senior Instructor from Manhattan Prep (exclusively GMAT students) with over 8 years of experience there with thousands of students, and thousands of classroom hours before leaving to start my own firm. I was always ranked superlatively at the firm on student responses and led several company-wide initiatives on course quality, score improvement. I also wrote content for the official published guidebooks.

I have a deep background in psychometrics (test making), with a particular focus on quantitative algorithms for measuring student ability used in the GMAT test. I studied test-making directly from Larry Rudner (maker of the GMAT algorithm.) I was also the original author of a series of testing algorithms that are based directly off the algorithms used for administering the GMAT.

I'm also a Duke and MIT Sloan graduate with a 99th percentile GMAT score.

Of the more than 20 years of tutoring experience I have, the majority of my direct student time was spent helping students prepare for the GMAT.

I work full-time in the combination of teaching, and building and running education technology businesses.
