Obituary for John Nilsen

John Thomas Nilsen passed peacefully on Friday, May 3, 2024, in the company of his loving wife and daughters. John’s journey began May 1, 1937, in the heart of New York City and ended at his home in Leavenworth, KS.

The 87 years of his journey were filled with a 57 year marriage to Marilyn, and 3 loving daughters, Danna (sons Jake and Jack), Heather (Shad and children Wyatt and Clare), and Lori (children Haley/Erik and Hanna/Tristan/Maelyn). His journey also included 37 years in the Leavenworth Unified School District as a science teacher, coach, referee and mentor. John personified living a life of humor, fun and putting family first. He treated all with respect and never met a stranger. He was deeply loved, had a life that was well-lived and will be greatly missed.

In accordance with John’s wishes, there will be a cremation and small family service. John’s family will cherish his memory in private and wish to thank all family and friends for their thoughts and prayers. In lieu of flowers memorials are suggested to the Leavenworth Education Foundation or Backpack Buddies, via Leintz Funeral Home.
