Registered Dietitians in Oncology Nutrition

All of the dietitians at Minnesota Oncology are Board Certified in Oncology Nutrition. The Oncology Nutrition Dietetic Practice Group has worked together with the Commission on Dietetic Registration to create a Board Certification credential (CSO) for Registered Dietitians in Oncology Nutrition. The first exam was given in 2008. CSO stands for Board Certified Specialist in Oncology Nutrition. A recommended minimum of two years of clinical practice with documentation of 2,000 hours of practice experience in the oncology care setting is required. The Minnesota Oncology dietitian team makes up three of 11 CSOs in the state of Minnesota.
