Patient Comments (3)
in Oklahoma City, OK |
From the beginning, I was surprised at the friendliness, professionalism, and accuracy laying out expectations. I felt like I was his only patient, not rushed, answered all my questions, and was spot on with detailing what would happened. I am cancer free now and couldn't be happier with the outcome.
in Ponca City, OK |
Dr. Yonemoto is very friendly, personable, and easy to visit with. He is very relaxed and you do not feel any pressure of him wanting to finish our visit. He will take the time to answer all questions and explain them to where one can understand. I highly recommend him.
