About Diabetes Education Services

We believe in your success!

We invite you to join our community of health care professionals who are passionate about improving diabetes care through education and advocacy.

At our company, we work diligently every day to provide diabetes information that is relevant, compassionate and cutting edge. Our goal is to help translate the complex science of diabetes into understandable terms that you can apply directly to the people you work with who are living with prediabetes and diabetes.

We know the road to becoming a diabetes educator and specialist is challenging. Many students aren’t sure how to get started or how to make the best use of their limited study time. See our Preparing for the CDCES Webinar to get started!
