Dr Martyak is wonderful, intelligent, asks smart probing questions. Because I am not the only patient who has observed this, it takes a long time to get an appointment. This is a negative, but of course it is because she is wonderful.

Dr Martyak is a perfect physician. Extremely knowledgeable, thorough, listens well. The reason appoint took a while was she has such a full schedule. I understand, appreciate her greatly, and the wait is absolutely worthwhile.

I felt Dr. Martyak listened very carefully to my issues, examined my medical records related to this issue and asked very thoughtful questions. Based on her understanding and knowledge, she developed a very clear plan of action to help me resolve the issues. We will start with the simplest actions, but she also ordered a follow-up study in case my symtoms continue. It was all taken care of very seamlessly in the office. I left feeling that I had really been taken care of.
