Why I chose UCLA: Incredible mentors and teachers we get to work with and a breadth of experience.

Dr. Sadik is a fan of many a racket-ed sport: tennis, ping pong, racquetball (still open to giving pickleball a chance). He loves exploring the countless places a day's reach from LA: Big Bear, Santa Barbara, Sequoia and Yosemite to name a few. Having a cup of matcha reading Jewish literature sounds like a beautiful morning to him.

Undergraduate: North Carolina State University
Graduate: Brandeis Heller School for Social Policy and Management

Why I chose UCLA: I chose UCLA for its culture of clinical excellence, diverse patient population, and high volume of complex procedures. The program's innovative, multidisciplinary approach to pain management offers unmatched preparation for both current practices and future technological advances. I was also drawn to the program's warm, expert faculty and the constant Southern California sunshine doesn't hurt either!
