About Me:

Dr. Day is an invasive cardiologist who is experienced in performing coronary angiograms, diagnostic left and right heart catheterizations, transesophageal echocardiograms, cardioversions and cardiac stress tests. While Dr. Day enjoys the diverse spectrum of patients and conditions he encounters as a cardiologist, he has a keen interest in risk factor modification and long-term management of chronic coronary disease and heart failure. Following in his father’s footsteps, Dr. Day pursued a career in medicine due to a deep desire to help others and ultimately chose to specialize in cardiology because of the complexity and variety it offers. When he is not caring for his patients, Dr. Day can be found spending time with his wife and dog experiencing all Oregon and the Pacific Northwest have to offer, including camping, live music, and the vibrant food and beverage scene. Dr. Day also enjoys watching and playing sports in addition to movie nights at home and cooking dinner with his wife.

I have had such a great experience with Dr. Day. I had no idea that a cardiologist could make you feel so cared for, be so attentive, or so knowledgeable. Literally, I felt like I would never get a cardiologist that could listen to me and give me the time necessary To explain exactly what was going on. He never makes me feel like he is rushing, And gives me all the time I need. Best experience I've ever had in the medical field.
