Where the Order Comes From
Google's ratings, as read
Ratings and review counts are Google's, read in October 2026, and we never edit them.
Right kind, right city
Only businesses Google files as a nutritionist or dietitian, with an address in San Diego and a rating of 4.0 or higher, are listed. One company appears once.
Rating weighed by volume
A big review history counts for more than a perfect score from a handful of people, so the order uses both.
What 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 California.
Questions Worth Asking First
- What is your credential, and do you hold a state licence?
- Are visits in person, online or both?
- Do you accept my insurance, and what does a session cost in total?
- How many sessions are typical, and what happens if I stop?
- Which tests or supplements are optional, and which are part of the plan?
- Will you share your notes with my doctor?
