Donald “Donny” Leo Mastel died unexpectedly of heart complications at the age of 54. He was born to Leo and Rita Mastel on May 8, 1968 in Linton, ND, growing up on the family farm and attending Zeeland Public School. He studied one year in Jamestown College before transferring to and graduating from University of Mary. His first job was for North Dakota Information Technology, then many years with NISC, and finally he spent the last three and a half years working for Innovative Energy Alliance.

He was united in holy matrimony to Sarah Johnson on April 30, 2011. They were blessed with two beautiful girls and resided in Bismarck, ND. His family was the center and joy of his life.

Don’s personality was larger than life. His ability to talk to anybody, his gift for storytelling, his great sense of humor, and his loving and generous heart made him beloved by many. Don was a very talented man. His garden was famous among fellow community gardeners, he had a gift for negotiating, and  he could sell anything to just about anybody. His strong business sense and people skills made him invaluable at work. He also had an amazing ability to remember the dates of random events from years past.

Don’s Catholic faith imbued every part of his life. He was a member of the Cathedral of the Holy Spirit where he attended Mass and a weekly family holy hour. Don was also a member of the Knights of Colombus. He was an exemplary husband and father and no sacrifice was too big for his family. He was devoted to his parents and made countless trips to Strasburg to help them with anything they needed. In business, he always did what was right- ALWAYS- even when no one was looking. He gave generously of his time and money when he saw a need. If he promised to pray for you, you would have many Divine Mercy Chaplets offered on your behalf. When you were Don’s friend, you were a friend for life. He would daily call up relatives, ex coworkers, hometown buddies, and friends who had moved. His day always started with a call to his brother “Melvin” and to his parents. 

Besides his faith, family, friends, and garden, Don loved farming. His favorite things to watch were cattle auctions, tractor sales, and farming blogs. He loved to talk farming with his dad and anyone else who knew anything about farming.

He is survived by his wife Sarah; daughters, Abigail and Maria; parents, Leo and Rita Mastel; brother, Dean (Pam) Mastel; niece, Becky (Seth) Anderson, and great-niece, Sofia Anderson; and niece, Katie (Chase) Grindberg.

He is preceded in death by his beloved twin brother, Daniel; his grandparents, Valentine & Helen Mastel and Ann & Simon Mitzel; and his two unborn babies Erin and Alex.

In lieu of flowers, family would like prefer donations to the ALS Association or to the St. Teresa of Calcutta Community for Mothers, at the University of Mary
