Nicholas J. Oleynik passed peacefully on April 29, 2026, at the age of seventy-four. Born on July 12, 1951, in Washington, D.C., he was the son of the late Vladimir and Helen Oleynik. He graduated from Lower Dauphin High School, earned his undergraduate degree from the University of Maryland, and went on to receive a Master’s degree from George Washington University. He is remembered for a sharp, calculating mind, a lifelong love of music, and a warmth that was felt deeply by everyone who knew him.
Nick dedicated 25 years to the United States government, serving at the U.S. Naval Hospital blood bank in Bethesda, the Office of Personnel Management, and the U.S. Mint before retiring from the Federal Bureau of Investigation (FBI) in 2007. His analytical nature extended well beyond his career; he authored books on probability and statistics and approached every subject he encountered with the same focused curiosity.
Music was a constant thread throughout his life. He was a member of the Hershey Chocolatiers Drum and Bugle Corps, performed in marching band competitions and school concerts, sang in choirs, and continued studying music well into adulthood. A multi-instrumentalist, he played drums, bass, and piano, and was learning to compose on a synthesizer in his later years. He had the rare ability to lose himself completely in music — counting every beat, feeling every note.
Equally creative and entrepreneurial, Nick built businesses around his photography and was never short of a new idea or project. He shot dozens of weddings and printed a custom poster of Camden Yards, created photo-printed mouse pads that he sold to the Denver Botanical Gardens, and produced greeting cards featuring planes that he sold to an aviation store; each venture a natural extension of his eye for beauty and his instinct for opportunity. He was skilled at fixing and building things, and took the same methodical approach to baking, brewing wine and beer, and pursuing the perfect replica recipe of his favorite “Ledo’s” pizza. His granddaughters were frequent recipients of homemade brownies and Twinkies, delivered in boxes labeled “Papa’s Bakery.”
In March 2019, Nick moved to Denver, a chapter that brought a visible softening. Surrounded by his grandchildren, his son’s family, and loved ones who welcomed him warmly, he settled into a life filled with jazz clubs, coffeehouses, road trips to small Colorado towns, and the simple joy of being close to the people he loved. He spoke often of his granddaughters Taylor and Reese, their cleverness and unique spirits a source of endless pride.
Nicholas is survived by his son, Daniel Oleynik, and his wife Lisa; his daughter, Carrie Oleynik Brinser, and her husband Allan; and his brother, David Oleynik. He was a proud grandfather to Taylor, Reese, and two grandsons. He was preceded in death by his parents and his brother, Gregory Oleynik. He also leaves behind Katherine Rogers Oleynik, to whom he was married from 1974 until 2019.
He endured the difficulties of his later years without complaint, walking on sheer will toward wherever he wanted to go. His legacy lives in the music he played, the books he wrote, and the love he quietly carried. May his last journey be not with pain, but with peace.
