David E. Koeppen

December 10, 1956 – June 13, 2025

David E. Koeppen was born on December 10, 1956, to Richard and Donna Koeppen and grew up in Rochelle, Illinois. He was preceded in death by both of his parents, as well as his stepfather, Willis Cline.

He graduated from Rochelle Township High School in 1975, where he participated in sports, Scouts, and the marching band. Shortly after graduation, David enlisted in the United States Army, where he served as an 11B sniper infantry soldier. His duty stations included the 101st Airborne Division at Fort Campbell, KY; the DMZ in Seoul, Korea; and Fort Lewis, WA.

After being honorably discharged from the Army, he spent a short time as a civilian before realizing he missed the camaraderie of service life. He then enlisted in the United States Navy, where he served as a Hospital Corpsman and Medical Lab Technician at Ocean Naval Air Station in Virginia Beach, VA.

David later worked as a janitor for 17 years at Oregon High School, where he especially enjoyed taking care of the books and savoring the peace and quiet that settled in after the students had gone home.

A man of quiet faith, he was a devoted Catholic who found peace in life’s simple pleasures—fishing, golf, reading, playing pool, and collecting coins. He had a lifelong love of sports and competition, playing on local softball and baseball teams and participating in dart, pool, and bowling leagues. He was extremely active at the Oregon Country Club, where he spent countless hours enjoying the game of golf and the camaraderie it brought.

He was a proud member of the Free Masons, and a dedicated Chicago Bears fan—loyal through every high and low.

David was known for his sharp sense of humor, a healthy dose of stubbornness, and an endless supply of random facts he’d pull out at just the right (or completely unexpected) moment. He found joy in everyday moments—spending time with his children, grilling out, and enjoying a quiet evening with a Stephen King novel.

Though naturally quiet and reserved, he came alive in social settings—quick with a joke, a story, or a challenge to a game of darts or pool.

He is survived by his three children: Justin (Kelly) Mercer, Garetty Koeppen, and Seth Koeppen, who brought him immense pride and joy throughout his life, His sister Doreen (David) Ribinson, and numerous cousins.

A celebration of life will be held at Franklin Street Pub on July 12th at 12pm. Friends and family are invited to gather, share memories, and raise a glass in honor of David’s life.

Interment of ashes will take place during a private family ceremony in the fall.
