He was born on October 2, 1935, in Ironwood, a son of Peter & Mary (Kapets) Sertic. He attended Luther L Wright High School and graduated in 1953. In 1954, Bob served as a Corporal in the Marines, stationed at 29 Palms in California. He was honorably discharged in 1957. After a few jobs, he ended his career as a UPS driver. Bob married his high school sweetheart, Nancy Holst, in 1955. Together, they had two children, Michael & Susie.

Bob was always interested in sports. He played football, basketball, baseball, and track in high school and excelled in all.

He donated over 200 WWI & WWII airplanes to Michigan Tech University to the ROTC program, along with the history of each plane. He always had a smile on his face and humor to go along with it.
