Excellent doctor, great staff. Dr. Martyak gave clear explanations and gave me plenty of opportunities to ask questions during my initial appointment and after my upper endoscopy/colonoscopy. I feel that she genuinely cares about her patients. She communicated the lab results to me promptly via MyChart, which was very helpful and reassuring. (If my results were life-threatening, I’m certain she would have called instead.) I understand what I need to do to improve my health. I did have to speak to someone at the office three different times before my colonoscopy prep prescription finally went through to my pharmacy, but technical issues happen. I did get the prescription on time. Sabrina, the scheduler who helped me, is efficient and proactive. Her kind and friendly demeanor made me feel very comfortable.

Great doctor. Takes her time and came up with solutions no one has suggested before. Intelligent, kind, and respectful. And front desk and nurses are always on the same level. Thank you!

Probably the most professional, kindest, attentive, knowledgeable doctor that I have ever come across. She went above and beyond to make sure that I was comfortable with her explanations. She ensured that every aspect of my GI health was accounted for. I can’t thank her enough for her effort and help.
