Great, friendly and very knowledgable dr.
in Owensboro, KY |
Dr. Onan Has delivered all 5 of my children and been with me through one of my miscarriages. He even offered to drive me to the hospital one time, i was having a miscarriage and i was alone during that visit. He is very understanding and takes time to answer all questions, even if that places him behind schedule seeing other patients. He goes out of his way to take are of his patients and make them feel comfortable.
