        Dr. Fennell was so kind. I was very nervous being this was my first visit with a cardiologist. She listened to my concerns and she gave me her assessment of what was going on. I had a lot of questions and she took the time to answer them. She was very friendly, thorough and spent so much time with me. She helped me not to be afraid. All the tests have been scheduled and I look forward to working with Dr. Fennell when the results come in.

        It was my first time seeing Dr. Fennell. I thought she was great. She seem interested in my well-being and concerned about my blood pressure. She is the first doctor to ever decide to switch a medication that I'm taking for one that is similar to it. She also wanted a copy of the results of my blood work ordered from my other doctors each time I have blood work done. I think she is going to a good cardiologist for me.
