Dietitian and Nutrition Services

Our Team

All of our nutrition consultants are Registered Dietitians (RD) authorized by the Commission on Dietetic Registration of the American Dietetic Association and licensed to practice in Texas by Department of State Health Services. They have met strict, specific educational and professional prerequisites and pass national registration examinations before they can use legally protected term "dietitian."

All of our Registered Dietitians are specifically trained in Lifestyle Medicine and the Whole Food Plant Based approach.
When you schedule your appointment, you will be matched with a nutrition consultant who meets your individual needs and will provide you with the most current nutrition information and interventions.
