Real outcomes from real patients. Every journey is different, but these are the changes we consistently see.
"The information I received was easy to understand and apply to my day. I learned how nutrition directly impacts my medical needs. I was very pleased."

AM Nutrition Services was founded in 2007 by Amy McCallister, a Registered Dietitian who started the practice out of a vision to make expert nutrition counseling accessible to everyone — covered by insurance, not just for those who can afford to pay out of pocket.
Today, our growing team of credentialed Registered Dietitians shares that same commitment. Every provider brings clinical expertise, genuine compassion, and the patience to meet you exactly where you are.
Everything you need to know before booking your first appointment.
Most major insurance plans cover Medical Nutrition Therapy (MNT) when referred by a physician or when you have a qualifying health condition. Our cost is also significantly lower than most online-only nutrition services for out-of-pocket patients. Contact us to verify your specific coverage — it takes just a few minutes.
A physician referral is common — and if your doctor referred you, you're already on the right track. However, you can also contact us directly. Self-referrals are welcome, especially for general wellness goals. We'll let you know what's needed for your insurance to cover services.
Your first visit lasts 30 minutes to an hour (depending on your insurance coverage). Your Registered Dietitian will conduct a full Nutrition Assessment — reviewing your medical history, eating habits, goals, and lifestyle. You'll leave with clarity on your personalized nutrition plan and next steps. Before your appointment, you'll receive a welcome email with intake forms, a short video, and a Nourishly app link code.
Yes. Telehealth appointments are available and just as effective as in-person sessions. You can meet your dietitian from anywhere in Arizona or Nevada — ideal if you have mobility limitations, a busy schedule, or simply prefer the convenience of home-based care.
Follow-up appointments are typically scheduled monthly, though frequency can be adjusted based on your needs, insurance coverage, and medical necessity. Your dietitian will recommend a schedule at the end of your first appointment. Between visits, the Nourishly app keeps you connected.
We have six clinic locations in the Greater Phoenix, Arizona area and one location in the Greater Las Vegas, Nevada area. Telehealth is available across both states. Contact us to find the most convenient location for you, or schedule a telehealth appointment from anywhere.
