About Caddell Prep

Caddell Prep was created after the founder, Glyn J Caddell, was laid off from an NYC engineering firm at the beginning of the recession. It provided the opportunity and incentive to switch gears and work on something that he really cared about; education. After tutoring for a few years, he quickly realized that he was teaching the same lessons over and over again to the many different students who came to Caddell Prep’s tutoring center. Rather than repeat the same lessons to each student individually or to a classroom of students, Caddell realized it would be more beneficial to record the lessons so they would be available to any student at any time.

While Caddell Prep’s main tutoring center is still helping many of the students on Staten Island, many of the math lessons are available for free to everyone. Education is not only extremely important to our founder, but also to the future of our country. Future advances in science and technology depend largely on the quality of the education available to students.
