On my initial visit to Daytona Heart Group, I was very impressed with Dr. Lazard. She has a laidback, calming demeanor that I have never before experienced in other Cardiologists. I came away from that interview with a renewed faith that I was in the right practice with the right Cardiologist.

My cardiologist for nearly 20 years, she listens to my concerns, takes the time to answer my questions, does not hesitate to bring in other specialists when needed. She is the reason I am still here.
