Our Story

In June of 2020, Charles Tang and Gracie Sheng founded Iridium Tutoring, an environment where students may consult a network of high school and college level tutors to assist their studies through free tutoring. During the transition to remote learning, they felt the need for accessible supplemental learning to support K-12 students.
