John Gerald Geddert was an American artistic gymnastics coach, who was a head coach of the gold-medal 2012 U.S. women's Olympic team and regular coach of team member Jordyn Wieber. He retired when he was suspended by USA Gymnastics in 2018 after being implicated in the USA Gymnastics sex abuse scandal centered on his long-time associate Larry Nassar. Geddert committed suicide in 2021, shortly after being charged with 24 criminal charges, including 20 counts of human trafficking of a minor, one count each of first-degree criminal sexual assault, second-degree criminal sexual assault involving a minor, and lying to a police officer.
