Dr Marak was a breath of fresh air when it comes to doctors. I felt like I was talking to a friend the entire appointment. I have had the hardest time finding a primary doctor since moving to the BR area 10 years ago. If I could have a cardiologist as a primary, he would be the one!! He explained everything to me and completely went over my chart because neither one of us knew why my primary doctor had even called me to schedule this appointment. I had a fall and went to the ER and while in the ER they did a complete EKG and before I could get home good, her office was calling telling me I needed an EKG. With that being said, he just discussed other things he saw in my chart and never once did he rush the appointment. Now, let me mention the nurse that did my vitals and connected me to the EKG machine and did the test. Her name was Tyrelle. She was also just like talking to a friend!! I have gone to appointments where the nurse barely speaks and then the doctor comes in and you can tell they are in a rush. Not this office. It was a vey pleasant visit and I would definitely tell others about Dr Marak if they need a cardiologist.

I thought the appointment seemed kind of strange. He didn't ask many questions and didn't seem concerned about my symptoms. I read his after visit summary and notes in MyChart, and it is NOT CORRECT. Which means he was not listening to me. I have sent a message to correct this. My health concerns, symptoms, and family history should be documented correctly
