Roby Mitchell, MD, aka “Dr. Fitt,” practices integrative/functional medicine in Amarillo, TX. He graduated with honors from Texas Tech University School of Medicine, Lubbock. While at Texas Tech, Dr. Mitchell participated in an exchange program with Jinan University Medical School in China. His exposure to traditional Chinese medicine opened his mind to modes of healing outside the narrow options of conventional Western medicine.
Dr. Mitchell’s own personal struggle with hypertension, overweight, insulin resistance and arthritis led him to revisit the philosophies of biochemical rebalancing with diet and supplements. His success in restoring his own health reshaped his practice approach, which is now focused on reversing “toximation”—the inter-connected processes of endocrine dysregulation, oxidative stress, and chronic systemic inflammation—through nutritional change, exercise, and hormone rebalancing.
