Our Team Of Registered Dietitians

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”.

In addition, most of us are Certified Diabetes Educators (CDEs), board certified in diabetes education by the National Certification Board for Diabetes Educators. This is the highest accreditation of professionals in the diabetes self-management field.

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.
