The was my first appointment with Dr. De Freitas and I thought his care was truly exceptional. He was so knowledgeable, patient and had a unique calm-kindness when explaining my test results. I was so nervous ( as always at my cardiologist appointments and tests) and he truly made me feel at ease and comfortable. He really listened to my questions and concerns and answered every single one with detailed explanations in easy to understand language. Additionally, he took the time to summarize our conversation and place in my patient chart, where I can look back at to review. I would highly recommend Dr. De Freitas in the future.

Dr. De Freitas answered every question regarding my case. He also answered every one of my husband's questions. He provided excellent clarification regarding my diagnosis and treatment. He is patient centered and definitely communicated with compassion, clarity, knowledge and extreme awareness of my medical condition. He never makes me feel rushed or as if I am taking too much of his time. I would absolutely recommend Dr. De Freitas.
