Born on July 3, 1961, in Rome, New York, David was the son of Geraldine and Reynold Klossner and grew up in Tupper Lake. David was an all-star athlete in high school football and went on to play collegiate football at Northwestern Oklahoma University, along with several years with the Watertown Red & Black semi-professional team. During training camp for the Houston Oilers, David experienced a knee injury, thus ending his professional football endeavors. David also spent several years as a competitive powerlifter and coach in upstate New York.

Like his father, David was a skilled and talented craftsman, carpenter and mason, evidenced by everything he did personally and professionally. David began his career in corrections at the Texas State Prison, and in 1990 he started working at the Federal Corrections Institute in Ray Brook. In 1994, Dave (and his three children from a previous marriage) met his wife Katie and shortly after transferred to FCI in Englewood, Colorado. Katie and David were married on Dec. 31, 1996, in Lake Placid.

David and family lived in Castle Rock, Colorado, from 1995 to 2012, where David was very active in the community with Castle Rock Players and as a football coach (Dolphin Youth Football Association, CRFD vs. CRPD Turkey Bowl fundraiser, and Douglas County High School). After 21 years, multiple career awards and lifelong friendships, David retired from FCI. In 2012, David and family moved to Commerce Township, Michigan, where he discovered a new career passion as a facility director for various senior living communities. In early 2018, Dave’s dream of having a cabin on the lake came true. He spent as much time as possible fishing, kayaking, swimming and enjoying lake life with family and friends. In the summer of 2019, David and family returned to Castle Rock, Colorado, to be closer to his son, better medical support and their church family.

David is survived by his wife Katie and youngest daughter Ellie Klossner of Castle Rock, Colorado; his oldest daughter Micah Klossner Bartocha (Tony) of Edwards; his son Dakota Klossner (Christina) of Fruita, Colorado; his daughter-in-law Tanya Klossner of Hokes Bluff, Alabama; his “Italian daughter” (exchange student) Giulia Orlando of Rome, Italy; his mother Geraldine Klossner of Tupper Lake; his siblings Rey Klossner of Gatesville, Texas, Reggie Klossner (Becky) of Hilton Head, South Carolina, Deborah Klossner of Canastota, Robert Klossner (Beckie) of Constantia, and Lauri Dukette (David), Dennis Klossner (Tracy) and Chris Klossner (Erin) of Tupper Lake; six beautiful grandchildren; many loving nieces and nephews; and other family relatives. David was truly blessed with so many good friends everywhere he lived or worked, especially close family friends Chuck and Cheryl Voyles of Lone Jack, Missouri.

David was preceded in death by his son Logan Klossner, his father Reynold Klossner, his siblings Sandra and Daniel Klossner, his in-laws Bob and Bobbie Damp, and his ex-wife Jerri Lynn Roots.

With the current COVID travel restrictions for New York state, the Tupper Lake service will be held at a later date. There will be a memorial service at New Hope Presbyterian Church in Castle Rock, Colorado, on Saturday, Nov. 7 at 2 p.m. In addition, a celebration of Dave’s life will be held at his beloved lake cabin in Michigan in spring-summer 2021.

In lieu of flowers, the family requests that donations be made to a college fund for David’s youngest, Ellie: http://bit.ly/dklossner.
