Summary

American performance trainer who worked with Michael Jordan and Kobe Bryant for decades — and whose books Relentless and Winning distill his observations of elite competitive psychology into frameworks for anyone pursuing extreme performance.

Core Contribution

Documented the psychology of the elite performer — the Cleaner mentality: not needing others' validation, having no off switch, making decisions without hesitation, taking responsibility for everything — as observed across decades training the most competitive athletes in history.

Key Spikes & Highlights

  • The Cleaner Hierarchy (Grover's taxonomy of competitors: Coolers follow the game plan, Closers make clutch plays, Cleaners create the situations where clutch is unnecessary — the Cleaner makes others perform better just by being present, does not need clutch moments because they've already controlled the outcome)

Notable Works & Achievements

Relentless: From Good to Great to Unstoppable

Winning: The Unforgiving Race to Greatness
