Buendorf was assigned to the Secret Service's Chicago Field Office, Presidential Protective Division and Denver Field Office. He was Special Agent in Charge, Omaha Field Office. Later, from 1983–1993, he was Special Agent in Charge of the Protective Division and, once again, assigned to protect President Gerald Ford and Mrs. Ford.
On September 5, 1975, President Gerald Ford, who had just given a speech at the California State Capitol in Sacramento, walked across a park where a crowd had gathered. A woman in a red dress, who later was identified as Lynette "Squeaky" Fromme, was seen following Ford while he was shaking hands. Upon seeing a Colt M1911 pistol, Secret Service Special Agent Larry Buendorf stepped in front of Ford. Buendorf yelled "Gun!", alerting the other agents who evacuated the area with Ford. He pulled the gun away and wrestled the woman to the ground, in the process slightly injuring his thumb and hand while placing the webbing of his thumb between the gun's cocked hammer and the slide of the pistol. For his role in preventing the assassination attempt on President Ford, Buendorf was awarded the U.S. Treasury Meritorious Service Award and the United States Secret Service Valor Award. During the years after the assassination attempt, Buendorf and President Ford maintained telephone contact every year on the September 5th anniversary of the attack. He also visited the former President and skied with him on occasion.
U.S. Olympic Committee
Buendorf later became Chief Security Officer of the United States Olympic Committee in 1993 after retirement from the Secret Service. From the Olympic Committee headquarters in Colorado Springs, his office is able to monitor security images from other Olympic training sites in Lake Placid, New York, and Chula Vista, California, a suburb of San Diego. The grounds of the Olympic Committee is open to the public and has a visitor's center and gift shop. As Chief Security Officer, Buendorf was responsible for security of the U.S. Olympic Committee. However, he was not directly responsible for security at the Olympic Games when they were held in the United States in 1996 and 2002, as such tasks were performed by local, state, and federal government personnel, as well as contracted private security. His philosophy for the Olympic Committee grounds security was "We don't want to create the environment of armed guards on the fence line." "That's not the kind of image we want for the Olympic movement. But we want it to be known there's a presence." Buendorf retired from his position in 2018.
