Fabulous cardiologist. A scientist and clinician, in a terrific blend. Spent a great deal of time going through the ins and outs of my complicated situation, and he did it with a solid sense of purpose and excellent sense of humor. Can't speak highly enough of him.

5 out of 5 stars

Dr Gallo was great at talking me though all the tools to access me for a base line. I had not been to a cardiologist since I was 30, had no issues, fear of the friends who did have issues and a few my age who had passed from a heart attack the window maker s it is referred to. Dr Gallo soend tons of time with me and I walked away at peace and with a great report of health and confidence Dr Gallo instilled in me after my visit. I encourage anyone to get a baseline, check things out, don’t be a statistic or afraid to get checked. Dr Gallo is the best. Highly recommend!
