[3] From 1984, Geddert was head coach at Great Lakes Gymnastics Club in Lansing, Michigan, where he first worked with Larry Nassar.

[9] In 2018, Geddert handed over ownership and management of the gym to his wife, Kathryn, in the wake of the Nassar sex abuse scandal.

On one occasion, Geddert shoved a gymnast forcefully enough for her to sustain a black eye, ruptured lymph nodes in her neck, and torn muscles in her stomach.

[13] Geddert retired from coaching on January 23, 2018, one day after USA Gymnastics announced that he was suspended pending an investigation into his alleged abuse.

[16] Hours after being charged, Geddert fatally shot himself at a rest area off Interstate 96 in Watertown Charter Township, Michigan.
