DECM Team

The DECM staff consists of nurses, dietitians, and consulting endocrinologists who work together to help educate and empower people living with diabetes. Most staff members are Certified Diabetes Educators (CDE), and together they have more than 70 years of experience in diabetes management and education.

Julie Evans, RN, BSN, CDE
Julie received her Bachelor of Science in nursing from the University of North Dakota in 1986. She has worked with diabetes patients for more than 25 years in both hospital and clinical settings. She became a CDE in 1998. Julie has a personal interest in helping patients manage their diabetes—her husband, Todd, has type 1 diabetes and she understands the daily challenges of living with the disease. She really enjoys teaching her patients the survival skills necessary to live full lives.

Mary Stuhr, RD, LMNT, CDE
Mary received her Bachelor of Science degree in food and nutrition in the Coordinated Undergraduate Program from Iowa State University. Before coming to DECM, she worked in diabetes education, outpatient medical nutrition therapy, and acute care nutrition at Alegent Creighton, Clarkson Hospital, and county and municipal hospitals in Iowa.
