Where This Order Comes From
Google's numbers, unedited
Ratings and review counts are Google's, read in October 2026. We don't change them.
Right kind, right city
Only businesses Google files as nutritionists or dietitians appear, each with a San Antonio address and a rating of 4.0 or higher. One company is listed once.
Size of the review history
The order weighs the rating by how many people gave it, so a long history counts for more than a perfect score from a handful.
What each scorecard shows
Each one 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 Texas.
Questions for Your First Call
- Which credential do you hold, and what is your license in Texas?
- Are visits in person, online, or both?
- Do you accept my insurance, and what would a session cost me in total?
- How many sessions do people usually book, and what happens between them?
- Will you coordinate with my doctor, and do you need my records first?
- Do you sell supplements, and is buying them part of the plan?
