Dr. Douglas W. Olen Sr. of Savannah, GA passed away peacefully at home surrounded by family June 19th, 2025.

Born to Walter and Sylvia Olen on February 5th, 1939, in Milwaukee Wisconsin, Doug was a graduate of Marquette University High School (’57) in Milwaukee. He went on to attend Marquette University ('61) and received his medical degree in 1967 from Marquette University School of Medicine. Doug was a well-respected and dedicated practicing radiologist at St. Joseph's Hospital in Milwaukee from 1973 until his retirement in 2001. Lifelong residents of the Milwaukee area, Doug and his wife Kathleen were thrilled to relocate to The Landings on Skidaway Island in Savannah, Georgia and loved sitting on their deck watching the sun set over the water.

A lifelong learner, Doug was always open to experiences. He travelled the world with his wife Kathleen and grandchildren, loved golf, painting, yoga, the arts, all kinds of music, especially the symphony, and exploring his spirituality. Doug was an avid reader and enjoyed discussing his latest book. He loved meeting new people and was quick to call someone a friend even if they’d just met. A man of faith, Doug was a member of The Cathedral Basilica of St. John the Baptist in Savannah. Doug’s and his family’s Jesuit education was a source of pride and inspiration. He was proud to serve as a Commissioned Officer in the United States Air Force.

Doug loved his family. He is survived by his loving and devoted wife of 64 years, Kathleen A. (Zierden) Olen, his children Kristen Robinson (Gary), Gretchen Funck (Bob), Doug Olen Jr. (Melissa) and Heidi Olen. He is also survived by 8 grandchildren whom he adored, Maraika Robinson (Tal Cohen) and Elliot Robinson, Sophie and Eleanor Funck, Mia, Beck, and Kai Olen and Finn Olen McNamara. He is also survived by his siblings Dale Olen (Joelyn), Eileen Olen and Mary Olen, his brother-in-law Peter Zierden, sister-in-law Charlene Zierden and numerous nieces and nephews. He is preceded in death by his parents Walter and Sylvia Olen.
