Joseph Robert Mack died peacefully October 21, 2020 surrounded by family, at the Spearfish Canyon Healthcare Center in Spearfish, SD, where he has resided since September 2018.

Joe was born to Sebastian and Helen (Dies) Mack in Lampman, Saskatchewan Canada on February 9, 1927. Early on Joe farmed with his father and two brothers and also worked in the bush country at Longlac, Ontario. He then left the farm to truck in the oil fields in the Steelman & Midale areas.

Joe married Marcia Marie Marcotte in the Sacred Heart Catholic Church in Torquay, Saskatchewan on July 3, 1957. While in Canada, they started their family where four of their twelve children were born. Joe worked as a mechanic at McCleary Motor's and was employed by Husky Oil in the gas and oil retail business. The couple moved to Deadwood, South Dakota in 1964. Upon arrival, they purchased the Mobile Service Station and a small motel on lower Main Street (where First Gold is now). They built the first car wash in Deadwood in 1965, and soon after, they built the first car wash in Lead. They bought the El Rancho Motel (currently Cedar Wood Inn) in 1968. They started their venture into buying rental real estate throughout Lead, Deadwood, and Spearfish in the 1970's and 1980's and a few commercial properties over the years. Joe painted cars for people to supplement the needs of their big family in his earlier years.

Joe had a passion for restoring classic cars, guns, hunting, and flying airplanes. Upon retirement, Joe & Marcia retired to Spearfish in the early 1990's. Joe & Marcia enjoyed their retirement with many road trips in their classic cars, on their motorcycle, and spending time with family. Joe loved listening to country music on trips & at home. He was a member of the St. Joseph's Catholic Church in Spearfish and Knights of Columbus. His faith and prayer were always a very important part of his life.
