Dr Ellis is very professional, observant, caring, and a great teacher about your illness. He explains everything so you can understand what is wrong and how it can be fixed or at least worked on. I was told "Game over" by another dr. Dr. Ellis did test to find out and assured me the game was NOT over. There were things we could do to better my condition and try to fix it if different steps didn't work. He did urge me to stop smoking, but did not put me down because I did smoke. I appreciated that so much. I didn't feel like a failure.

I travel from Tennessee to see Dr. Ellis. I have been a patient since 2006. I can't say in words how much he has done for me. He is a great Cardiologist, and a very good listener. Some physicians are too busy to take the time to actually listen to their patients. I credit him for diagnosing my condition and directing me to the Physicians to proceed with my CABG. I normally do not send comments, but I feel very strongly that the treatment and guidance I've received from Dr. Ellis and his staff has been an answer to my prayers.

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.
