David Eugene Siewert

Dr. David Eugene Siewert, son of Reverend and Mrs. B.C. Siewert, entered this life on March 2, 1934, in St. Paul, Minnesota. He graduated St. Olaf College in 1955, where he double majored in Biology and Chemistry, and also learned to play the piano and enjoyed the music and sports programs there. Dave spent the next five years at the University of Minnesota, Minneapolis Medical School. He had a one-year hiatus fighting an infection on a heart valve before graduating in 1960.

Dave’s next year in a rotating internship at St. Luke’s Hospital was special, because there he met and married his wife, Mary “Lenore” Christianson on June 3, 1961. Dave had a three-year residency in internal medicine in Minneapolis, where he and Lenore welcomed their first daughter, Mary Beth.

The Siewert family moved to Bozeman, Montana in June of 1964 and Dave spent the next 35 years working at the MSU Health Service. He and Lenore were blessed with two more daughters, Susie and Cindy.  

Dave enjoyed the friendly staff at the student health as well as all the students he helped care for and was affectionately called “Mr. Rogers.” Dave was also on the staff with the Bozeman Deaconess Hospital and the Gallatin Valley Medical Society, serving both in leadership capacities. Dave shared a position as team physician and attended all Bobcat football and basketball games. He continued to be a proud supporter of Bobcat sports for 60 years and bled Blue and Gold. Could it be that the Bobcats won their conference championship game against the Grizzlies because Dave was cheering them on from Heaven?

Summers were spent in a variety of places: helping small town doctors take vacations, working in Yellowstone Park, as well as working in a clinic at Campus Crusade headquarters, and in the back hills of Honduras with missionary friends. After retiring in 1999, Dave worked part time with his “little brother” Larry Walker, PA, in Three Forks and Manhattan for ten years. He also kept busy volunteering, playing bridge, and participating in the Evangelical Free Church programs, where he was a member. Dave truly lived a life of service, trusting and thanking God, because “He works all things together for His purpose to those who are called by His Name.”

Dave passed from this earth on March 13, 2024, and lovingly leaves behind his daughters Mary Beth (Dan), Susie (Mark), Cindy (Morgan), and very special grandchildren Caitlyn (Andrew), Mattie (Michael), Mary Ellen, Tarje, and Ivy of whom he was very proud and thankful for. He attributed his long life in most part to lifelong aerobic activity, the grace of God, and modern medicine, having gone through four aortic valve replacements. Dave was preceded in death by his wife Lenore, his parents Burdette and Florence Siewert, his sister Marilyn, and his special friend Myrt.  

The family would like to thank all of the many loving friends both old and new, the community at The Springs where Dave spent the last year and a half of life, Dr. Erb, Hospice nurse Emmanuel, and the kind, hardworking staffs at Bozeman Deaconess Hospital and Gallatin Rest Home.

A celebration of Dave’s life will be held at 1:00pm on March 23, 2024, at Dahl Funeral & Cremation Service. In lieu of flowers, donations may be made to the Heart of the Valley Animal Shelter, 1549 E Cameron Bridge Rd, Bozeman, MT 59718; or Love INC, 141 Discovery Dr, Bozeman, MT 59718.
