We love Dr. Thamilarasan. He is an amazing physician. He makes you feel like you're the only patient he has and you're his sole focus while your with him

I found Dr. Thamilarsan to be competent and as caring and concerned as Dr. Lever was. Dr. Thamilarsan appears to put as much effort, diligence and thoroughness into each patient as Dr. Lever did, and that was what I was anticipating and hoping for. His questions and willingness to show and explain my tests results equaled those of what Dr. Lever did and that put me totally at ease. I have no problem with continuing with Dr. Thamilarsan as my cardiologist.

Reviewed on Nov 2, 2021

Dr. Thamilarasan was simply outstanding. He was empathetic, incredibly patient, an active listener, knowledgeable, and inquisitive about my circumstances. Without me realizing it, he gave me time and space within our appointment to absorb and process the test results, waiting patiently to see what, if any, questions I had ,and to also ensure I understood those results and the possible paths forward. He provided recommendations and guidance, but noted that what was most important was that I felt comfortable with the proposed path forward and notably, he demonstrated a willingness to patiently discuss options and provide feedback until I was comfortable. When I highlighted that I noticed at least 4 aspects of my echocardiogram at Cleveland Clinic that day that typically don't happen at home, he took the time to ask what they were and then explained why the Clinic does each of the four. When I had a follow-up question two days after my appointment, he responded timely. One other noteworthy aspect of our visit, particularly given my circumstances, he met with me before the echocardiogram and then made time to meet the same day after reading the echocardiogram to discuss the results.
