Celebration of Life: Wednesday, August 5, 2026, 10:30 AM, Celebration Farm, 4696 Robin Woods Lane NE, Iowa City, Iowa 52240.

Tim was born on December 25, 1948, in Cedar Rapids, Iowa, to Leo and Mary (Strickland) Thomsen and was the oldest of five children. After graduating from Mount Vernon High school, he attended Cornell College, where he was a member of the wrestling team, and then attended medical school at the University of Iowa. Following general surgery residency and cardiothoracic surgery fellowship, Tim practiced general, thoracic, and vascular surgery in Mason City before establishing the cardiovascular surgery program at North Iowa Mercy Hospital in 1989. He did a stint in hospital administration in the mid 1990’s as the CEO of the Mason City Clinic. Thereafter, he resumed his surgical practice and moved back to Iowa City in 2004 to practice trauma, burn, and emergency general surgery at the University of Iowa and vascular surgery at the Veterans Administration Medical Center. Within the University setting, he was able to utilize his remarkable gift of teaching.
Tim’s medical career culminated with his work in palliative medicine in which he became board certified in the early 2010’s. He became the director of the Supportive and Palliative Care program at the University of Iowa until his retirement in 2023. This point in his career truly became the pinnacle of his brilliance, weaving together his years of practicing many types of surgery, his years in administration, and his coming to peace with the delicacies of human life that cannot be cured with modern medicine. While he imparted innumerable valuable lessons throughout his career, one of the most significant was his insistence that the young doctors he trained learn to value each member of the medical team as essential and valuable. Tim viewed every member of the team, from the telephone operator to the physician, as crucial to the practice of medicine. He had an incredible gift for making people in all walks of life feel seen and special, and he continued sharing this gift for the duration of his life. Tim deeply believed the patient and their prognosis should shape and define the delivery of personal and compassionate care. Another poignant illustration of Tim’s philosophy as a physician is the three-legged stool he was known to carry around the hospital on rounds. Given the common chair-less hospital room, this stool allowed Tim to sit and offer his presence and care for whatever duration of time his patients and families needed.
Tim will be remembered as an incredibly dedicated and devoted father to his children. He instilled a love of books, music, birds, exercise, humor, and adventure. He was also a deeply beloved grandfather to his 14 grandchildren.
Tim is survived by his former wife, Jean (Scott) Bennett and their four children, Sarah (Ryan) Majerus, Timothy W. (Lauren) Thomsen, Daniel (Megan) Thomsen, and William “Will” (Alycia) Thomsen; his 14 grandchildren; siblings, Bill (Lori) Thomsen, Mary Thomsen, and Martha Davis; and best friend and partner, Kathleen McCarron.
Tim was preceded in death by his parents; sister, Barbara (Jeri) Neal; and brother-in-law, Vic Davis.
In lieu of flowers, consider a memorial gift to your local Hospice to support the work he valued so deeply.

My husband, Dan and I both have great memories of training under this man. He left an impression on everyone that he came in contact with. He was very special. Our condolences to your family.

I will forever remember Tim’s twinkling blue eyes. I had the privilege of working with him at Mercy hospital and NIMC. He treated and respected everyone as a valued colleague. He also was my Dr. He resected my lung for a tumor in 1992. He later asked if he could use the procedure information in his lectures at Iowa. A man of many talents, intelligent, and compassion. He will be missed. ❤️
Tim was a grade behind me at MVH. He was an outstanding person in all aspects. He also was the surgeon for my my brother-law in Iowa City. It is no wonder that he became such a sucessful doctor remembering what I do about him. My condolences to his family!
Tim let me shadow him in the operating room when I was in high school. He said I was welcomed anytime and I came as often as I could. He clearly had deep, respectful, established relationships with his OR team, his communication during the surgeries I witness was clear and compassionate. He never lost his cool, he was always having fun. He loved his work and his patients. All of this informed my career in oncology and hospice and palliative medicine. When we reconnected a few years ago, it was as if we picked up as kindred spirits. His memory will live on through me. Sending his family kind thoughts.
I have very fond memories of Tim! We shared birthday date and always called each other as brothers!
He was a colorful person with multiple talents and unlimited energy! May his soul rest in peace.
I met Dr. Thomsen, “call me Tim”, 20 years ago in the surgery clinic. I was a nurse with the liver transplant team, and somehow we discovered our shared love of Hawkeye wrestling. He always had time to say hello, and ask how you were doing. God speed Tim.
Bless the Thomsen Family through this deep loss.
I met Tim in 2006 when my husband was very ill and Tim had to do three surgeries in a very short period of time. He had to leave his stomach open due to the compartment syndrome in order for him to live if it wasn’t for Tim his caring I would’ve got the extra 18 years and I got with my husband. He was an amazing doctor an amazing friend and he will be so missed. It was really sad to hear this news I thank God every day that he’s the one that had my husband because he always did the best for us and always made us feel very special. My prayers go out to the family and his friends.
After a day of tears in finding out of Tim’s death …I have few words that can express my sadness. Tim was a childhood friend. We grew up together with my brother Steve and his sister Barb. We were family. When Steve died at age 21 in a MVA, Tim stepped up. My family, and my shattered heart will forever be grateful for how he held us together, even as his own heart was broken. We kept in touch through a lifetime. He journeyed with me at my father’s end of life. He visited Mom at the nursing home and attended her Wake in March. (He and mom were each others hero’s) He remained constant, kind, strong, and exceptional. I am so very lucky to have known him for a lifetime. And he carries my childhood, our laughter, shenanigans, and tears, as he soldiers upward. I imagine Tim, Steve, and Barb together and that comforts my heart. My deepest sympathies to his brother Bill, sisters Mary and Martha. And to his children and grandchildren who carry his DNA and his heart. Rest in peace, Tim. Barb Wolfe

Thinking of Dr. Thomsen and the whole Thomsen family and how welcomed I was into your lives and home. Everything from rope swinging over the creek to tumbling over my borrowed bike’s (Dan’s?) handlebars into the ditch. Stacking firewood for the winter to shooting baskets in the summer. Myst, Maelstrom, and ClarisDraw on the Mac to aerobie over at the sod fields. My youth was shaped by your family’s generosity and kindness and was capped by Dr. Thomsen leading a group of us to and through the Grand Canyon after graduation. I hope you are all doing well and reliving the many fond memories in your heads. I know I’ve never stopped.
My sincere sympathy to you all. You have had a lot of sadness the last couple of years and that is enough. Always keep Tim’s smile in your heart and know he is riding on your shoulder. RIP Tim.
