- 5 out of 5 starsReviewed on 6/26/2025
I greatly appreciate Dr. Demyan. I respect her expertise; I appreciate the time she takes to listen; and I am grateful for her kindness and compassion. Dr. Demyan answers all of my questions and explains things thoroughly. During my past visit, after reviewing my symptoms, she explained her plan of care. I was hoping that Dr. Demyan would consider prescribing antibiotics based on my medical history. For good reasons that she explained, she did not.She directed me to contact her if things didn't get better. Even though I hoped that Dr. Demyan would be open to a different course of action, I respected her enough to follow her direction. I was and remain confident in her as my Internal Medicine doctor.
