Mark was a 1973 graduate of Thorntown High School where he was an avid athlete playing baseball, basketball, and track. He worked for Allison Transmission, Division of General Motors, in Speedway, Indiana for 35 years.

He was a loving husband, father, grandfather, and great grandfather. Mark loved the game of golf and enjoyed participating in a golf league in Indianapolis as well as any time he could be out on the course with family, especially his brothers. He grew up working on the family farm and that led to a great enjoyment for working outside at his own home in his later years. He was known for having one of the best lawns around and took great pride in his work. Mark was a diehard IU fan. He was always up to have a conversation about sports, but IU and the Colts were his favorite topic. He was always one to lend a hand or help his friends and family when in need.
