Brad Lewis is a novelist, biographer, playwright, screenwriter, and former actor. His focus has ranged from the bizarre world of celebrity doctors to detailed histories of Jewish-American development, with particular interest to the entertainment industry.He co-wrote the bestselling biography of Milton Berle, My Father, Uncle Miltie, with the comedian's son William Berle, a candid look at the irreplaceable American television icon. Lewis' novel Great White Doctor is a scalpel thriller centered on the sordid lives and weird sexual habits of "celebrity doctors", exposing the seamy side of high profile specialists who perform unnecessary surgery on their female patients.

Lewis has written often about the Hollywood scene, and is no stranger to celebrities and celebrity doctors. Anonymous underworld "businessmen," often sent their lady friends for treatment in his offices. That experience with known mobsters contributed to Lewis' interest in how gangsters, Hollywood, and Washington somehow connect in the American landscape. Hollywood's Celebrity Gangster, The Incredible Life and Times of Mickey Cohen and Mickey Cohen: The Gangster Squad and The Mob are two books dealing with the history of organized crime.

As an actor, Lewis appeared on television in As the World Turns, Love of Life, The Guiding Light, and trained at the prestigious H. B. Studios in Manhattan, with its founder Herbert Berghof and fabled acting teacher William Hickey. He appeared in many off and off-off Broadway productions. Lewis has advanced degrees from CUNY (Psychology) and New York University; a fellowship at Columbia University, College of Physicians and Surgeons, and St. Luke's-Roosevelt Hospital. A popular talk show guest, he has appeared on numerous radio and television programs. Lewis is a native New Yorker.
