Dr Thamilarsan is an amazing doctor. He is kind, courteous and caring. He cares about his patients. He makes sure he acknowledges my spouse. I had a wound on my leg and he looked at it and took time to bandaged it even that was not his field. He said since I am not used to doing this but just dealing with the heart I will try my best. He also had his staff take to direct us where I could go to have it taken care of.

No bad experiences. Good experiences---Everything went like clockwork. The technicians giving the EKG and ECO were very detailed in their instructions speaking loud enough and slow enough for me with hearing aids to understand them. The nurse who took vitals and reviewed information prior to Dr. Thamilarasan's visit was just as efficient and understandable. As always, Dr. Thamilarasan checked me over and explained the results of the tests. Very good.

Dr Thamilarisan literally saved my life by rearranging his schedule to get me in to see him sooner rather than later after another local doctor blew off my symptoms. He also arranged for an appointment with a heart failure doctor at the same time.

Dr. T had obviously read my chart before I arrived and hadn't scheduled me for a stress test based on my recent horrible back problem. He asked if I felt well enough now to do the test instead of the echo because it helped him more when treating me. I was astonished. When was the last time one had a dr. not only read their chart in advance but consult the patient on how to proceed....Probably never..He is amazing.
