Where the Order Comes From
Google's numbers, as found
Ratings and review counts come from Google, read in October 2026, and we never edit them.
Right kind, right city
A business needs a Google category that fits, a Nashville address and a rating of 4.0 or higher. A company appears once.
Size counts with score
The rating is weighed by how many people gave it, so a large history counts for more than a perfect score from a handful.
What each card shows
Each scorecard 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 Tennessee.
Questions for Your First Call
- What credential do you hold, and what is your state license?
- Are sessions in person, online, or both?
- Do you accept insurance, and what would a session cost in total?
- How many sessions do people usually book?
- Will you share notes with my doctor?
- Do you work with my specific food concerns or diagnosis?
