It is with great sadness that we must announce the passing of Dr. Russell Kittleson on November 5, 2026. He passed away peacefully at home, surrounded by family. He was a renowned orthodontist and educator for more than half a century and, more importantly, he was a loving and dedicated husband, father, and grandfather. He brought boundless energy and a sense of humor to the care of his patients and the education of generations of orthodontic residents. After graduating dental school at Marquette University and completing his orthodontic residency at the University of Illinois he was instrumental in starting the orthodontic residency program at Marquette. He had the good fortune to practice with his brother Nathan for many years and later with his son John. He was a dedicated member and leader of several dental and orthodontic organizations including the American Association of Orthodontists, the American and Wisconsin Dental Societies, and the Pierre Fauchard Academy. He served as President of the Wisconsin Society of Orthodontists, the Wisconsin Section of the American College of Dentists, the Midwestern Section of the Edward H. Angle Society, and the Marquette University Dental Alumni Association. He was recognized by Marquette University as their Distinguished Alumnus in Dentistry and also received the Part Time Faculty Excellence in Teaching Award from the dental school. He was awarded the Earl Shepard Distinguished Service Award by the American Board of Orthodontics.

His teaching and love of travel took him around the world. He brought smiles to so many people in so many ways over the years and will be greatly missed by all who knew him. He is survived by his wife of over 67 years, Jean; his three sons Roger, Gary, and John; their spouses Zayde, Kristen and Connie; as well as five grandchildren August, Iris, Isabelle, Ben, and Tyler.  In lieu of flowers, please consider a donation to the Marquette University School of Dentistry in memory of Russell Kittleson to the Russell Kittleson Endowed Professorship in Orthodontics.
