Date of Death: April 30, 2026
It is with great sadness the family of Denis Dierker announce his passing on Thursday, April 30, 2026 in Porcupine Plain, SK at the age of 88 Years.
Denis George Dierker was born Dec. 31, 1937 on the family farm outside Cudworth, SK. He was the fourth of 11 children born to Anton and Rose (Medernach) Dierker. Denis spent his early years helping out on the family farm. He first attended school at St. Cunigunda, and later attended boarding school at St. Peter’s in Muenster for grades nine through 12. In 1959, Denis graduated with his Bachelor of Arts in Chemistry from the University of Saskatchewan in Saskatoon. In the interests of getting a job, he then chose to go back to school for an additional year to get his teaching certificate. While attending university, Denis was active in St. Thomas More college and the Newman Club. It was here that he met the love of his life, Marianne Frances Lehane. Denis and Marianne were married in Cupar, SK on Aug. 1, 1960 and settled into married life in Yorkton, SK where Denis taught high school chemistry and a few additional subjects for the next 30 years. Denis valued
education and completed his education degree by taking summer classes at the University of Regina.
Denis and Marianne raised four children and supported them in their post secondary educational pursuits. Denis loved farming and, in addition to helping out with the family farm in Cudworth, he and Marianne purchased their own farmland at Swan Plain, SK in 1969. Denis was a farmer in the summer and on evening and weekends in the spring and fall, often driving the 90 miles between the farm at Swan Plain and the house in Yorkton multiple times a week during seeding and harvest. In 1979, they decided to purchase land closer to home, moving to the Ebenezer area where they stayed until they retired back into Yorkton in 2012.
Denis was a man of faith and participated in activities associated with St. Gerard’s. He and Marianne led the baptismal program for many years. He curled with the church group and was a member of the Knights of Columbus, helping out with many a bingo over the years. He also served as an officer in the cadets in the early years of their marriage. Once he retired from teaching, Denis took up golfing and went out several times a week with a group of retired teachers. He and Marianne also enjoyed travelling. Cruises were one of their most favoured means of travel although they also thoroughly enjoyed road trips
including semi annual trips to Texas.
Denis was predeceased by his parents Anton and Rose and his parents-in-law Daniel and Cordula Lehane. He was also predeceased by his brothers Richard and Edwin and his brothers-in-law William Lehane, Harold Keyser and Jesse Etayo; his sisters Agnes Zubach and Margaret Capeling; his sisters-in-law Yolande Dierker and Alice Keyser.
He leaves to mourn his passing Marianne, his wife of 65 years; his children Daniel (Brenda), Catherine, Mary Ryhorski (David) and Allen and his sons Joshua (Nathalie Medrano) and Jayden. He is also survived by his daughter-in-law Aarti; his sisters Magdelene Etayo, Rosemarie (Maurice) Stadnyk, Jane (Bill) Simington and his sister-in-law, Charlotte (Dierker) Funk; as well as his brothers Joseph (Louise), Francis (Debbie) and Raymond (Jean); his brothers-in-law Nick Zubach and Ralph Capeling; and numerous nieces and nephews and other extended family.
