The SIMD mourns the passing of Dr. Jim Coldwell, M.D., a fouding member of SIMD, a pioneer in metabolic medicine, and an active member who will be missed by all. A newspaper obituary is posted below.

A Funeral Mass will be Saturday, 10 a.m., October 20, 2018 at St. Patrick Catholic Church in Sand Springs with Reverend Todd Nance officiating. Jim will be laid to rest at Woodland Memorial Park Cemetery in Sand Springs. Arrangements have been entrusted to the care of Mobley-Groesbeck Funeral Service of Sand Springs. Dr. James G. Coldwell attended the University of Oklahoma College of Medicine, graduating in 1955. He served a year of internship at Denver General Hospital before completing a residency in pediatrics at St. Louis Children’s Hospital from 1956-1958. He was commissioned as a Captain in the Army from 1958-1960, serving in Verdun, France. Upon completing his time in the military, Dr. Coldwell undertook fellowship training at Johns Hopkins University School of Medicine to learn the basic skills of what would become his lifelong passion - the evaluation, treatment and follow-up of developmentally disabled and handicapped children. After leaving the military, Dr. Coldwell moved to Tulsa in 1960, becoming Chief of Pediatrics and Medical Director of Inherited and Metabolic Disorders at Children’s Medical Center. Under Dr. Coldwell’s leadership, the emphasis of Children's Medical Center expanded well beyond its prior role of convalescent and rehabilitative care of children, to include growth and growth disorders, endocrine abnormalities, and children with developmental, metabolic, and neurological disorders. During his early days as Medical Director, he was also instrumental in creating specialty clinics for children with polio and rheumatic heart disease. He recruited numerous pediatric specialists while at CMC, including those with specialty training in Neurology, Electrophysiology, Physical Medicine Rehabilitation, Speech and Language, Endocrinology, Nephrology, Rheumatology, Nutrition, and Genetics. Dr. Coldwell’s extensive knowledge of, and experience in, the evaluation and treatment of complex medical conditions, particularly those relating to genetic, endocrine and metabolic disorders, was recognized and highly sought by those in the academic and professional community, both locally and nationally. His meticulous attention to detail in evaluating children with complex medical conditions and his incredible patience in pursuit of answers to diagnostic dilemmas, helped to foster his reputation for medical excellence. Early in his career, Dr. Coldwell developed a lifelong fascination with phenylketonuria (PKU), a medical condition that, without proper diagnosis and timely treatment, results in permanent intellectual disability. Establishing one of the first comprehensive treatment facilities for children with PKU in the U.S., Dr. Coldwell helped hundreds of children and families understand this complex medical condition, and through proper treatment, avoid irreparable mental and developmental impairment. As a longstanding faculty member of the University of Oklahoma College of Medicine-Tulsa, Dr. Coldwell was an active participant in the education of medical students and residents, serving as both a mentor and role model. He readily participated in medical research to find better diagnostic tools and treatment and published numerous scientific articles that helped to set the standard for medical care of children with complex medical conditions, including PKU. Aside from his impressive professional knowledge, Dr. Coldwell was universally known for his genuine concern and compassion for children with special needs and their families. His optimism, willingness to listen, and earnest desire for the best outcome of each child entrusted to his care, endeared him to his patients, family members, and professional colleagues. To the very end of his career, Dr. Coldwell continued to selflessly serve others and advocate for those in need, serving as a volunteer physician at the Xavier Clinic in north Tulsa, a facility that provides uninsured indigent families the opportunity to receive much needed medical care. Dr. Coldwell’s life, and a lesson for us all, can best be summed up in his own words “Children’s Medical Center no longer exists, but children in need do. Society needs to value children more and provide the necessary funding to assure a healthy future for all children.“ He is survived by his two sons Robert (Danqing) in Dallas and Matthew (Heather) in Seattle; three grandsons Bowen, Benjamin, and Connor; sisters Cathy Paul in Tulsa and Cecile (Paul) St. Louis in Denver, and brother Alan Coldwell in Denver.
