Chosen by New York Magazine as one of New York City's Best Doctors in 2002, Ken is a microsurgeon as well as a former 10 year vice-president of The Explorers Club. He has been a consultant for NASA, climbing high on Mount Everest and flying in zero-gravity, and is a writer for National Geographic Adventure and Popular Mechanics. His TV appearances include Nightline, 20/20, Today Show, Larry King Live, and Oprah. Ken's two books, Doctor on Everest and Surviving the Extremes, explore the most inaccessible places on the planet - especially inside the human body, where there are more unexplained mysteries than anyplace else in the universe.
