Dr Ramalho was very professional & explained things in a matter that was understandable to my husband & I. He took the time, too, to confer with my regular cardiologist.

Dr Ramalho is kind and compassionate and not afraid to be candid. I really appreciate him, especially that he wants to know about my cancer treatment so that he is working in concert with my Roswell team. I have chemo fog sometimes, and I was there the day following my infusion, which made it a bit harder on him, but he handled it well.
