He might only be 5 feet 7 inches tall, but Jeff Gewirtz is a giant in the sports law world.

As an undergrad at Tufts University, Gewirtz, a lifelong tennis aficionado, envisioned becoming an agent for professional tennis players. Through his research, he found that the most high-profile agents at the time all had law degrees. So he followed their lead and pursued a law degree at Brooklyn Law School. Once he realized how much he enjoyed his classes and internships, he changed direction and decided he wanted to practice sports law.
