Dr. Martyak is amazing. I don't have words to tell you how wonderful she is. She had my medical records dating back several years and had them memorized; she completely understood my concerns and addressed each and every one with so much wisdom, knowledge, and empathy. She is everything I could ever ask for from a doctor. I wish she could be my primary care physician!

Dr Martyak is patient, thoughtful, knowledgeable and efficient. I was pleased with my visit. She has a great "bed-side manner." I am confident that she will provide me with excellent health care. My only disappointment is that her schedule Is booked for weeks in advance so it took a while before I had my first appointment and my colonoscopy isn't taking place for 3 months. In fairness, she offered using a different doctor for the colonoscopy and I declined to do so.
