I went to see Shelley and was pretty well set on the idea that this was just a waste of time. Boy was I wrong. Shelley helped me understand my diabetes problem and how to make food work for me instead of against me. She made all the difference in the world for me. I would highly recommend visiting her if you have a diet related issue.

Your Questions Answered
Registered Dietitians (RD’s) are health professionals specializing in food and nutrition. In order to earn the nationally-recognized credential of RD, a candidate must complete a Bachelors Degree in Food and Nutrition and/or Masters Degree in Nutrition or American Dietetic internship. RD status also requires successfully passing the National Registration Exam and accumulating a sufficient number of on-going Continuing Education credits annually. A RD is sometimes referred to as a nutritionist, however, a nutritionist who has not achieved RD status may not advertise herself or practice as a Registered Dietitian. Also, in Texas, Registered Dietitians are licensed (LD) to prevent misuse of the term nutritionist.
RD’s and LD’s are the only health professionals permitted to counsel patients on medically-necessary dietary intervention. There are no laws about what credentials are needed to go by the title of “nutritionist”.
A Certified Diabetes Educator (CDE) earns the designation by successfully completing the Certification Examination for Diabetes Educators. Candidates must meet rigorous credential and professional practice experience requirements to be eligible to take the examination. Achieving the CDE credential demonstrates to patients that the health care professional possesses distinct and specialized knowledge, thereby promoting quality care for patients with diabetes. There are currently only 22 diabetes educators who hold the CDE credential in Austin. Shelley Madsen & Associates are very fortunate to employ four of them!
