I really liked having Dr. Ellis as my cardiologist, even though I have a Hawaii cardiologist; because I live there. I first came to Cleveland Clinic when my Hawaii cardiologist recommended a procedure that was not available in Hawaii; and, that was Dr. Ellis' specialty.I've made 6 trips to Cleveland Clinic, 4 during this Covid-19 pandemic; and it's expensive as well as risking infection given my underlying health conditions.The results of Dr. Ellis' procedure lasted me, 4 years.So, if any advances in his field come online, I'm going to return to Cleveland Clinic.
