Glenn Greenberg

Brave Warrior Advisors, LLC

Glenn Greenberg and partner John Shapiro founded Chieftain Capital Management in 1984. By pursuing a disciplined investment strategy, Chieftain compounded its accounts at 22.5% (before management fees) during the period from 1984 through 2004 versus 12.9% for the S&P 500. Chieftain Capital later divided into two separate entities, with Shapiro leading the new Chieftain Capital Management and Greenberg leading Brave Warrior Advisors.
