International Diabetes Center
At Park Nicollet International Diabetes Center, our mission is to ensure that every person with diabetes or at risk for diabetes receives the best possible care. We are known throughout the world for our experience and expertise in patient education, professional training, research, and models for patient-centered care and quality improvement. Our focus is on translating new research findings into clinical practice and discovering innovative ways to use technology to improve diabetes care.

International Diabetes Center (IDC) believes in a patient-centered, team approach to diabetes care. We focus on the relationship between the patient, provider and educator to ensure that each receives the information and tools they need to improve patient health.

Founded by Donnell D. Etzwiler, MD, in 1967, IDC continues to provide world-class diabetes care, education, publications and research that meet the needs of people with diabetes and their families. We continue to shape the community – and the world – to help people live well with diabetes.  

IDC staff includes over 80 health care professionals involved in research and education, and who collaborate with other areas within Park Nicollet to ensure patients receive the best possible diabetes care.
