WinnMed is pleased to share that allergy specialist Michael D’Netto, M.D., M.B.A., has joined the Mayo Clinic Health System practice full time in Decorah, and is accepting new patients.

An allergist helps patients manage allergic and immunologic diseases.  As a Mayo Clinic-trained allergist, Dr. D’Netto provides testing and treatment options for infants through adults who experience food, environmental, medical, venom (insect bites or stings) and other allergies.  He provides skin testing, food and medication challenges, and lung function and immune system testing all at WinnMed in Decorah.  In addition, Dr. D’Netto provides care for patients with asthma and skin conditions like eczema and dermatitis.


Originally from Cincinnati, Ohio, Dr. D’Netto received his Bachelor of Science from University of Notre Dame. He then went on to concurrently receive his Master in Business Administration and his medical degree from Ohio State University, completed his residency in Internal Medicine from Mayo Clinic School of Graduate Medical Education, and his fellowship in Allergy and Immunology, also from Mayo Clinic.  He is certified by the American Board of Internal Medicine, and a member of both the American Academy and American College of Allergy, Asthma and Immunology. 

Dr. D’Netto says, “Personally, I have multiple food and environmental allergies. I hope to help others manage their own allergic and immunologic conditions as well as possible, as others have done for me. I have already started meeting people in the community, starting with the recent community picnic at WinnMed.  This is a welcoming community and I look forward to helping people identify and manage allergies so they can live a full life.”
