Timgrover

Tim Grover began working with Michael Jordan in 1989 and remained one of the most trusted figures in Jordan's inner circle through his championship years with the Chicago Bulls. That long partnership is what originally established Grover's reputation as a world-class performance coach and is the real-life foundation behind his bestselling books.

Yes — Tim Grover trained both Kobe Bryant and Dwyane Wade alongside Michael Jordan, making him one of the rare coaches whose fingerprints are on multiple all-time-great careers. He draws directly on those relationships in his writing and speaking, using them as proof that his performance philosophy works at the absolute highest level.

Relentless lays out Grover's framework for elite performance, most famously introducing the concept of the Cleaner — the highest-tier competitor who operates on pure instinct, refuses to settle, and takes complete ownership of outcomes. The book pulls directly from his decades working with Jordan, Kobe, and Wade, so it reads more like a field manual from the locker room than a typical self-help title.

W1NNING is Grover's follow-up New York Times bestseller that pushes past the ideas in Relentless to define what sustained winning actually costs and what it demands psychologically over the long haul. Where Relentless focused on building a relentless competitor's mindset, W1NNING goes deeper into the sacrifice, isolation, and dark stretches that champions have to navigate to stay on top.

Yes — Paolo Banchero, the Orlando Magic forward and former number-one overall NBA draft pick, is listed among Tim Grover's active champions.
