What My Patients Say

Dr. Markwell is an exceptional doctor. His professional courtesy and understanding is outstanding. - RC

It was my first visit and Dr. Markwell provided excellent service. He was a good listener, answered all my questions, and gave explanations to all concerns I had. I'm confident he has been the right choice for me. - IB

Dr. Markwell performed an adenoidectomy on my 9-year-old son. I could not have asked for better service than what we received from Dr. Markwell and his supporting staff. I loved Dr. Markwell's bedside manner, patience, professionalism, and caring spirit. He took the time to explain everything that would happen during our initial consultation and then explained it again as he was completing the initial examination. On the day of my son's surgery, Dr. Markwell was equally patient, professional, and caring, and that meant a lot to a child who was anxious and fearful. I'm glad my son had an outstanding experience that in retrospect showed my son that he had nothing to worry about. Thank you for a wonderful experience. - BDH
