James Duane Nanson, M.D.

James Duane Nanson, M.D. (73) of Kansas City, MO passed away surrounded by his beloved family on May 20, 2020. 
He is survived by his devoted wife of 43 years, Debbie, sons Ben and James (Holly) Nanson, daughter Kelli Nanson Disidore (Tom) and cherished grandchildren; Zoe and Bingham Nanson and Declan and Dominic Disidore. James was born in Columbia, MO to James Clayton and Mary Ruth Wilson. His older sister, Carol Jean Olive precedes him in death and younger sister, Nancy Jo survives. 
James was an alumnus of Hickman High School and the University of Missouri-Columbia. He received his B.S. in Chemistry before graduating from medical school in 1973. He was a member of the American College of Physicians and completed his residency and fellowship in Internal Medicine at the University of Missouri Hospital and Clinics and Truman Veterans Hospital. He completed his post doctoral fellowship in Nephrology in 1979 and was designated a diplomat and board certified in both Internal Medicine and Nephrology. During his time as resident, James met and wed the love of his life, Debbie Davis in 1976. He opened his first office at the Boone Clinic and continued his journey in private practice while he and Debbie raised their three children; Benjamin, Kelli and James. James’ love and dedication to his patients was outmatched only by his love for his family. He was a devoted father and husband and gifted physician who worked tirelessly to serve, help, and heal others.
In 2001, James retired from private practice and moved with Debbie to Kansas City to be close to his children and treasured grandchildren whom he adored. We will remember his kind and gentle nature, his compassion for animals, and his unconditional love for his family. He was patient beyond measure, eccentric and genteel and always saw the good in people. He taught his children to respect all life and led by example with humility and generosity of spirit. As his health declined in his last year of life, he retained his keen wit, humor, and optimism. He never complained and fought till the end. We find solace in knowing that he will continue to cheer, watch over, and protect us….ever our father, until we meet again. 


A celebration of life will be held by the family in the months to come.
