    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

  • Dec 20, 2018

    This was my first visit with Dr. Chadderdon. He was kind, empathetic and thoughtful. I had blood work, an echo and met with his PA prior to our visit. I interacted with five other health professionals in his office during my visit. Everyone was great. After two people tried to put in an IV I asked that the third attempt come from a specialist. I know it added more time to my appointment and I did not please the person performing my echo but she kept her professionalism. And everyone was very accommodating even though I was then off schedule. My visit with Dr. Chadderdon's PA was incredibly educational. I felt pretty comfortable with the idea of what my condition was and possible treatment of it by the time I met with Dr. Chadderdon. I felt he had really read and remembered my health history even though we were meeting for the first time. I left his office/care feeling confident in his teams future care.

    Dr. Chadderdon is very straightforward, honest and reliable and extremely skilled in his profession. I would recommend my family or anyone else to him at any time they have a cardiac issue.

  • Dec 13, 2018

    Yes the doctor was absolutely wonderful - he was very calm, explained everything in detail so that we could understand, there was no question about what he was saying, very very kind man - put you at ease instantly, and when we left we felt so confident about his qualifications and his knowledge to us. So I would recommend him hardly to anybody and I've already been talking to people about what a wonderful doctor he is.

    Well Scott Chadderdon was really methodical and practical it in his approach to me. He explained explained the situation as best you could and it was pretty well done for a presentation. Actually actually Scott kind of just just his personality. He kind of inspired me somehow it's where I I got home the next day and I thought the condition I've got plus plus history his demeanor in the way he used his hands when he was talking to me and everything. I realized it would be a good idea for me to change my mode of life somewhat and start eating better maybe in start exercising and I've done that so he was humanly inspiring to me and thank him for that more than*
