Coming from New York, I have high expectations of medical professionals, I've been fortunate to receive care from some of the nation's leading physicians. Suffice it to say, Dr. Nywening has exceeded every expectation. He is intelligent, personable, compassionate, affable, and remarkably patient. Most importantly, he has been an outstanding partner in my treatment plan and overall medical care, consistently taking the time to listen, explain, and ensure that every decision is made thoughtfully and collaboratively. I would highly recommend him without reservation to anyone seeking a physician who combines clinical excellence with genuine compassionhe is the reason I continue to return to this practice.

Love this doctor. Though a few weeks before the appointment, I called the nurse to ask about an MRI cause I always get one of those and she told me there was not one in the file and wouldn't ask the doctor and guess what after my appointment the doctor needs the MRI so I don't know. I have to go get one and have another appointment.
