Mark D Boldt, RN, CNP


Mark grew up in Southern Minnesota and stayed close to home for college. He graduated from Mankato State University in 1979 with a Bachelor of Science in Nursing. From 1979-83, he worked at North Memorial Medical Center on neurology and orthopedic units. He then transitioned to work with similar patients in the private sector. In 1985, Mark and his family moved overseas to learn French and tropical medicine. This was preparation for a position as director of nursing school in what was then Zaire. Coming back home, Mark joined Digestive Healthcare (which eventually became Minnesota Gastroenterology, P.A.) in 1987. He has had several positions over the years - nurse clinician, research coordinator with the Cancer Prevention Research Unit, and nurse endoscopist with the Colon, Prostate, Lung and Ovarian Cancer Screening Study. During his employment he returned to school obtaining a Master of Arts in Nursing from the College of St. Catherine. This degree began his career as a Nurse Practitioner in 1991. Mark has worked almost exclusively with liver diseases with a special emphasis on hepatitis C treatment.
