Our Team Of Registered Dietitians

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.
