Gregory John Tewsley was born in Calgary on October 7, 1952, and passed away peacefully at home on February 14, 2022, at the age of 69 years. He will lovingly be remembered by his wife, Marny Tewsley; his daughters, Alison (Kevin) Jesske, Shawn (Brad) Hausauer, Anne (Dan) Dubeau; his grandchildren, Travis, Colby (Shay), Haylie, Jacob, Owen, Nole; and great-granddaughter, Avery; also his sisters, Kathy (Colin) Bryksa, Joan Desjarlais, Wendy (Jack) Magro; brother-in-law, Les Schwabe; as well as several nieces and nephews. Greg was predeceased by his mother and father, Jack and Theresa Tewsley; his youngest sister, Christine Tewsley-Schwabe; brother-in-law, Ken Desjarlais; and niece, Quinn Tewsley-Schwabe. In the summertime, Greg enjoyed yard work and he was fierce about harvesting the fresh peas from the garden; BBQing the old fashion way with charcoal briquettes and fire starter (don’t forget the fire starter); playing countless hands of cards on the deck; and many rounds of backgammon. He was always up for any kind of building project and in healthier years, leant a hand wherever needed. His sense of humour was legendary and his practical jokes will be remembered fondly. Trips to the mountains always brought Greg much peace and joy, and his daughters plan on taking him on one last trip this summer. A private celebration of Greg’s life will be held at Saamis Memorial Funeral Chapel.
