Yes, I'm very happy with my doctor. Can't say anything bad about him. He's always been there for me, and even when I was in the hospital, before he come down to visit me, which had nothing to do with his office, and he's a great doctor, okay? That's all.

Jason was thoughtful in responding to my comments and questions, as well as suggestions on how I might improve my cardio profile.

Dr.Wasfy spent time reviewing my medical history, quickly identified the problems, and came up with a solution. He clearly enjoyed cracking the mystery and took pride in solving a challenging medical condition. He shared genuine happiness when seeing my condition improve significantly since my last visit. I am very grateful to him.

Dr. Wasfy has been a wonderful doctor since I first met with him about 10 years ago. He and his NP [redacted] are very attentive and patient and are always encouraging any questions that I may have. I think the world of both of them and I feel very fortunate to have them as my cardiology team.
