Well-known inmates hire this consultant to help them navigate life behind bars

Sean "Diddy" Combs will be sentenced in two days and could spend the next 11-plus years in a 10x10 cell.

When Harvey Weinstein, Luigi Mangione and NXIVM cult leader Keith Raniere faced hard time, among the first people they called was Craig Rothfeld.

Rothfeld is the founder and owner of Inside Outside Ltd., a company that helps clients, including the aforementioned three, navigate the unnerving world of life behind bars.

With only about a half-dozen prison consulting firms in the United States, Rothfeld is part of a little-known niche industry spawned around the criminal justice system that caters to big-name and no-name clients, all with the same goal.

“I’m advocating for their human rights," Rothfeld said.

Rothfeld said he knows firsthand the misery and anguish prisoners experience because he was once incarcerated himself. He served 18 months after he was indicted for various financial crimes and was released in 2017.
