R. Chester in Bear
I recently moved to DE and was looking for a cardiologist. One of my colleagues recommended Dr. Innasimutu. Right from the minute I walked in, I was made to feel very comfortable. Dr. Innasimutu and his staff are excellent. He is a very confident young man with a very pleasant demeanor. Most importantly, he listened patiently to my medical history and then took time to explain to me my condition and his plan of action. My previous Cardiologist was nice but wasnt this detailed. I highly recommend.

Victor in Wilmington
I have had nothing but great experiences with this entire staff, including the other physicians. Today I was scheduled for several tests over the next few weeks for various symptoms, before I even arrived home my email contained articles on what the tests were for, explaining each one thoroughly. My last visit I was emailed a healthy heart diet. If you have questions, he not only answers them, but explains the why to his answers. He gets 5 stars from a retired hospital employee.
