On September 11, 2001, Marine officer Robert J. Darling was called into the Presidential Emergency Operations Center beneath the White House, where he served as a liaison among Vice President Dick Cheney, the National Security Advisor and the Pentagon as the attacks unfolded.
Darling's military career spanned more than 20 years and included flying Cobra attack helicopters during Desert Shield and Desert Storm, service in Somalia and assignment as a presidential pilot with Marine Helicopter Squadron One.
He is the author of 24 Hours Inside the President's Bunker: 9/11/01: The White House, his firsthand account of leadership and decision-making during the attacks. Today, Darling speaks and teaches about crisis leadership, communication and making critical decisions under extreme pressure.
I think these are a better fit for your page than the material you were given. Donnie Campbell and Robert Darling especially needed trimming because the original copy had enough detail for a full speaker bio, not a lecture-series listing. The shortened versions give visitors the important question quickly: “Why would I want to hear this person speak?”
