The Best Nutritionists and Dietitians in Phoenix, AZ (2026)

Where the Order Comes From
Google's own numbers
Ratings and review counts are read from Google in October 2026 and never edited by us.
Right kind, right place
A practice must be filed by Google as a nutritionist or dietitian, have an address in Phoenix and hold a rating of 4.0 or higher. Each company appears once.
Size counts, not just score
We weigh the rating by how many people gave it, so a long history counts for more than a perfect score from a handful of reviews.
What the scorecards show
Each card shows the rating, the size of the review history, the share of four and five star ratings, and whether Google lists a website, phone and hours.
Check the license
Registered dietitian (RD or RDN) is a national credential that a person has to earn and keep. The word nutritionist is used more loosely, and the rules for it differ from state to state. Before you book, ask which credential the person holds and where you can look it up, and ask whether they are licensed in Arizona.
Questions for Your First Call
- What credential does the practitioner hold, and are they registered to practice in Arizona?
- Are sessions in person, online or both?
- Do you take my insurance, and what does a session cost in total?
- How many sessions do people usually book?
- Will you coordinate with my doctor or other providers?
- What happens between sessions if I have a question?
