I want to say that my visit with Dr. Heretis was great. She made me feel comfortable, she didn't rush, I felt free of asking questions and she answered them. Dr. Heretis is very knowledgeable and explains everything to you where yoy xan understand. I was very happy with her. Dr. Heretis has a really good bedside manner. I am happy she's my new Cardiologist! I love the office it's always clean and it has a nice relaxing ambiance. The staff are very nice as well. 👌
