Robert William Dahlgren

Robert William “Rob” Dahlgren, 73, of Bartlesville, Oklahoma, left this life early Wednesday morning, January 21, 2026, at his home.

Rob was born October 29, 1952, in Pensacola, Florida, to Richard Wallace Dahlgren and Bonnie Mae (Hoffman) Dahlgren. At the age of two, his family moved to Superior, Wisconsin, where they remained until 1958 before settling in Yukon, Oklahoma. Rob graduated from Yukon High School in 1970, where he served as his senior class president. He attended El Reno Junior College where he earned an Associates of Arts Degree and then attended the University of Oklahoma for one year before transferring to Oklahoma State University. He graduated in May 1974, earning a Bachelor of Science Degree in Chemistry.

Rob moved to Bartlesville in 1975 and began a 42‑year career with Phillips Petroleum/Applied Automation in Analytical Methods Development which was merged into Siemens USA. He married Karen Kay Soule on October 8, 2000, in Bartlesville.

Rob was a long‑time member of Our Savior Lutheran Church until its closure, after which he and Karen worshiped at St. Luke’s Episcopal Church in Bartlesville. He carried a strong and steady faith in Jesus Christ throughout his life. Rob faced his pancreatic cancer diagnosis with strength, grace, and dignity, supported by the love of his family.

A lifelong learner and self‑described “maker,” Rob loved building, creating, and discovering how things worked. He read constantly and delighted in researching new skills—whether carving small wooden figures, creating cigar-box guitars, making longbows and knives, crafting bicycles from scratch, or fixing up old Volkswagen buses. He held a pilot’s license and was a member of numerous groups and clubs over the years, including the Jaycees, a beer brewing club, a Volkswagen group, and Via de Cristo, where he served as Rector and participated in many retreats.

Rob had an adventurous spirit and loved being outdoors, especially camping and kayaking at Copan Lake. He enjoyed riding motorcycles, cycling in the Oklahoma Freewheel, sailing in the Caribbean and around the Greek Islands, and traveling in the RV with Karen to visit friends and family. He fiercely loved his family and cherished the many friendships he built throughout his life.

Rob is survived by his wife, Karen Dahlgren of Bartlesville; two sons, Ryan Dahlgren of Tulsa and Stephen Dahlgren of Oklahoma City; one step‑son, Dennis Soule and his wife, Kelley, of Skiatook; two brothers, Greg Dahlgren of Yukon; Terry Dahlgren and his wife, Susan of Yukon; one sister, Cindy Crick of Arlington, Texas; as well as numerous grandchildren, great‑grandchildren, nieces, and nephews. He was preceded in death by his parents, Richard and Bonnie Dahlgren, and by his sister‑in‑law, Christy Dahlgren.

A memorial service will be held at 11:00 a.m. on Friday, February 6, 2026, at St. Luke’s Episcopal Church, with Father Nick Phares officiating.
