Where the Order Comes From
Google ratings and counts
Ratings and review counts come from Google as read in October 2026, and we never edit them.
Right kind, right place
Only nutritionists and dietitians with a Boulder address and a rating of 4.0 or higher are listed, and each company appears once.
Weighing the numbers
The order weighs the rating by how many people gave it, so a large review history counts for more than a perfect score from a handful.
What the scorecard shows
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 Colorado.
Questions for Your First Call
- What is your credential, and are you licensed or registered in Colorado?
- Do you see clients in person, online or both?
- Do you accept my insurance, and what will a session cost in total?
- How many sessions do people usually book, and how often?
- Will you coordinate with my doctor?
