Mark attended St. Joseph’s Catholic School while in elementary, Williston Junior High and then Williston Senior High, graduating in 1974. Upon graduation, he entered the military, serving in the Army for 4 years, where he learned his trade as a heavy equipment mechanic. He loved his country and proudly served. During his service time in the Army, he met Jimmy Musco and Henry Poth to which he remained great friends with for over 50 years. After leaving the miliary, he went on to attend Dickinson State College and graduated with a heavy equipment operators’ degree. Mark worked for Wisco, Guardian Inspection, which later became Ico, and most recently being named as Tuboscope, until his health declined. Throughout his career he was always a dedicated employee.
He will be remembered as being a strong man, physically, emotionally and spiritually and lived his life by a moral code of ethics. If his family or anyone he knew experience a need, he would be there without fail, for whatever it was they needed.
Later in his adult life, he married Duanne (Dodi) Whittle, which he opened his heart to a became a step-dad to Brian and Bradley. After divorcing, he met Gail Senti Mead to whom he remained married to until her passing in 2023. It was to that union that he welcomed Jake, Marshall, Elizabeth and Bethany into his life; creating his big instant family. Gail and Mark together share one child; a son, Benjamin. Mark was so proud of all of his children and grandchildren. He was a dedicated, hardworking family man who had a huge heart having been a loyal husband, father, grandfather, brother and friend. His passion in life, when not working or spending time with his family was hunting and fishing. At a very young age, he went “frog” hunting, bringing his “collection” home and filling the mud room floor with water to keep them alive. While not initially impressed with his desire to save all of his new “friends” he brought home, his parents finally were able to find humor in it, sharing the story and talking about this for years. He became a master skill level deer hunter, trapper and fisherman. Everyone would call Mark for advice, even the most seasoned hunter and fisherman. His hunting buddies, Mic Whittle, Vinney Kirkegaard, Darryl and Duffy Pomeroy and Mike Quitt, became his “brothers” and life-long friends.
Left behind to cherish his memory are his children, Benjamin, Jake, Marshall, Elizabeth and Bethany; along with his brother, Kirk (Renee); sisters, Lisa (Scott) and Myia (Curt). Mark is preceded in death by his wife Gail; his parents, Jack Sr and Ramona; his brother, Jack Jr; sister, Tana; grandparents, Benjamin and Leona St. Peter and Herman and Lavisa Marler; his nephews, Brock and Ethan.
