Sheridan James, MD is a board-certified internal medicine physician and functional medicine practitioner based in Scottsdale, Arizona, offering concierge care built around a fundamental question: what is actually causing this? Rather than managing symptoms indefinitely, Dr. James focuses on uncovering root causes, restoring physiological balance, and creating the conditions for patients to genuinely thrive. Her philosophy blends the rigor of Western internal medicine with functional and integrative approaches — addressing disease prevention, nutrition, hormone optimization, stress resilience, and sustainable lifestyle change as a unified strategy. Whether a patient's goal is extending healthspan, reducing medication burden, achieving a healthy weight, or simply feeling better day to day, Dr. James delivers care that is proactive, personalized, and built for the long term. Her practice operates as a concierge model, keeping her panel deliberately small so every patient receives the time and attention their care actually requires.

About the Physician

Dr. James was born and raised in Tucson, Arizona and earned her medical degree from the University of Arizona College of Medicine. She completed her residency in Internal Medicine at the HonorHealth Scottsdale Internal Medicine Residency Program (2020–2023) and is listed as a trained practitioner with the Institute for Functional Medicine (IFM). Her additional training spans hormone optimization, advanced diagnostics, and lifestyle medicine. Before medicine, Dr. James was an NCAA Division I collegiate soccer player — a background that instilled a deep, practiced understanding of nutrition, movement, and the physiology of peak performance. That athlete's mindset now informs how she approaches every patient: not as a collection of diagnoses to manage, but as a whole person with the potential to perform at a higher level. She founded her Scottsdale practice to demonstrate that internal medicine, done well and without time pressure, can achieve outcomes that conventional primary care rarely reaches.
