November 9, 1942 ~ January 13, 2019

Trinus (Slim) Mulder of Medicine Hat went to be with the Lord on January 13, 2019, at the age of 76 years. Trinus, son of Heinze and Pietje, was born on November 9, 1942, in Hardegryp (Friesland), Holland. At age nine, he immigrated to Canada with his family. In 1966, he married the love of his life, Petronella den Hollander, and they were loving, remarkable spouses for 52 years. They were blessed with 4 children, Brian, David, Donna, and Brenda; 9 grandchildren; 1 great-granddaughter; 4 step- grandchildren, and 6 step-great-grandchildren.

Trinus and Nel worked side by side and built a wonderful, fulfilling life together. Trinus was known for being honest and hardworking in his work as a farmer, a drywaller, a real estate agent, home builder, and a businessman. Trinus, Nel and their family enjoyed many adventures together going for walks and drives, camping and traveling to many places. Prior to retirement, Trinus enjoyed his pets and yard and his first fish pond. In 2006, Trinus and Nel had the opportunity to build their retirement home. In retirement, Trinus golfed with family and friends, spent hours in his hobby plant room looking after his flowers, built his second fish pond, maintained a large, beautiful yard and was a friendly competitive bowler. Family and friends will especially remember Trinus for his bright smile, enthusiastic conversations and storytelling, playful energy, nature-loving, joke-telling, playing tricks, singing, intelligence, wisdom, generosity, and love. Trinus took great pride and joy in his grandchildren, showing them his yard and feeding the fish. His life was founded in the Christian faith; with his declining hearing, instead of going to church, Trinus could be found each Sunday morning watching Charles Stanley and Tribal Trails or listening to the Gaithers. Above all, Trinus was a devoted son, husband, father, grandfather, brother, uncle, and friend.

Trinus leaves to cherish his memory: wife, Nel; son, Brian (with Karen, Evan and Travis); son, David (with Tammy, Kate and Beth); daughter, Donna (with Tyler, Laura, Lisa [with Rony and Mila], Thea, Drew); daughter, Brenda (with Jim, Trent, Riley, Kacie [Cody, Lenni], Brendan [Mel, Amelia, Elara], and Sean [Kelly, Dawson, Grayson, Ruby]). He is survived by his 3 brothers: Harry (Coby), Harm (Linda), and Joe (Marlene). Trinus is also survived by Nel’s siblings: (Cobi), Art (Maryke), Bill (Sandy), (Annie), (Bea), Maryke (Ton), Jan (Anja), Jaap (Lida), and Anjo (Henny), along with many nieces and nephews on both sides. Trinus is predeceased by his parents, Heinze and Pietje (de Jong) Mulder; brother, Harm; Nel’s parents, Art and Petronella (Rysdam) den Hollander, and Nel’s siblings: Ger (Siem), Wynand (Rie), Arie, An (Arie), Magda (Adrie), Piet, Mart, (Peter).
