Our CEO Josh began tutoring while studying mathematics at the University of Chicago. When he graduated, he taught and designed the curricula for the upper level honors math courses at a private high school in Chicago. The following year, he decided to tutor math exclusively so he would have more flexibility as he prepared for graduate studies, but eventually realized he had found his calling in this profession. He moved to San Francisco in 2013 for a breath of fresh air and founded Test Prep Unlimited, and has been training expert instructors ever since.
