Leadership at the summit
Chris Warner has cheated the death zone, where oxygen is thin and the weather brutal, to stand atop the world's two highest peaks, Mount Everest and K2 - the only Marylander to have done so. The Annapolis resident and certified Alpine guide owns Earth Treks, with climbing gyms in Columbia, Timonium and Rockville, and leads expeditions of business school students on team-building outings to the high peaks of South America and Africa. With Don Schmincke, a Maryland-based business consultant, Warner has written a book, "High Altitude Leadership: What the World's Most Forbidding Peaks Teach Us About Success."
