Although recently retired from our practice after 19 years of service here and nearly 50 years of oncology/hematology practice, Dr. Jim Neidhart founded our Clinical Research program and built it to the widely respected status it enjoys today. A nationally recognized Oncologist/Hematologist, his career includes the former Directorship of the University of New Mexico Cancer Research and Treatment Center, Director of Medical Oncology at MD Anderson Cancer Center and Clinical Director of the Ohio State University Cancer Center.  His nearly 200 publications and clinical research activities attest to a distinguished career as one of the nation’s most respected oncologists. Once voted by his peers as “One of the Best Doctors in America”, Dr. Jim provides a constant source of experience and knowledge for San Juan Oncology Associates.

He and his wife Sue have six children and nine grandchildren scattered among Brazil, Viet Nam, New Zealand, Oregon and Colorado. Dr. Jim enjoys horses, working on the Neidhart farm with his son Jeff, and visiting family in the far-flung reaches of the world.
