Robert Joe Dyer, 73, of Great Falls passed away on October 29, 2020, after fighting multiple illnesses. Robert was born on Valentine’s Day in 1947 to Joe and Pearl Dyer in Springfield, MO. After honorably serving in the Army during the Vietnam War, he returned stateside to Fort Campbell, KY and met his soon-to-be wife Sandra at a Shoney’s restaurant in Clarksville, TN. Always the eternal flirt, he was able to sweet talk his waitress into a date and shortly afterwards into 41 years of marriage until Sandra passed away in 2009. Their marriage produced two sons Robbie Jay (Charmaine) Dyer of Casa Grande, AZ and Jeffrey Scott (Colleen) Dyer of Great Falls, MT. Survivors also include his granddaughters, Courtney V. (Brandon) Batey of Great Falls, MT and Brandi Renee (Sterling) Perkins of Florence, AZ; brothers, Stanley, Max, and Harley; and sisters, Patsy, Linda, and JoEtta. At his request, no public services will be held. A military graveside service will take place at a date and time to be determined. In keeping with the never-give-up spirit that he learned in the Army, he kept flirting with all his waitresses up until the very end. After all, it worked out pretty well for him one time.
