Diabetes education and dietitian services

NCMA Endocrinology and Diabetes Center offers the services of a full-time dietitian and certified diabetes educator. Educational services can be requested independently or in conjunction with requests for physician evaluation and management services. We offer one-on-one services and regularly scheduled group classes.

Learn more about our diabetes education and dietitian services. See below to learn more about our diabetes self-management class.

Our diabetes self-management class is available for patients with Type 2 diabetes. It is ideal for patients who are newly diagnosed or need a refresher and haven’t completed a qualifying class in the past. It works much like a support group. The program consists of four classes of approximately 2–2 ½ hours each, for a total of 9 hours.
