AM Nutrition Services

AM Nutrition Services is a clinical nutrition counseling practice founded in 2007 by Registered Dietitian Amy McCallister. The practice emphasizes evidence-based, individualized guidance grounded in physiology and long-term health rather than short-term diet trends. Its counseling focuses on practical skill-building and personalized support designed to help people improve nutritional health in sustainable ways. Serving the Greater Phoenix region, including Tempe, and Greater Las Vegas, the practice remains centered on clinical rigor, community health, and meaningful care.
