    I had been dealing with an abnormal heart rhythm for some time and had been to a local cardiologist, whose care was very disappointing. Dr. Chadderdon was a wonderful contrast, being very attentive, providing me with important information and helping set up a surgery for the next day. I can't say enough about his care. My experience was entirely positive and I am extremely grateful that I have become his patient.

    Scott Chadderdon is an excellent Cardiologist. Scott and the Cardio team at OHSU undoubtedly saved my life when I suffered a heart attack while in OHSU waiting for Heart surgery. His attention to my situation dating back to May 2018 has been outstanding. He is always there for my questions and meetings. Is always truthful and supportive. Works with a team that are outstanding. I cannot make enough positive comments about the Cardio team at OHSU. In fact the medical team at OHSU that I have met since moving to Oregon are excellent and a credit to OHSU
