Have had Dr Shammas as my Cardiologist for over 25 years. I continue to be impressed with his obvious knowledge and response to my personal condition related to my cardiac health.

Dr Shammas is great. He listens, then talks to you like you're a person. He explains in non-medical terms. I would recommend him to anyone.

For a doctor, he’s pretty awesome. He saved my life a few times. I’m so sad that he’s going to retire. I wish him all the best of luck he deserves it.

Very personable. He sat down and visited about how I was doing the last 6 months. He explained what the previous heart tests revealed. He explained what medications he wanted to change and why, in simple layman terms. Short, friendly visit that I actually enjoyed.
