I met Dr OConner when my mother needed a doctor. Years later when I needed a doctor I knew where I wanted to go.
I love that he listens to what I have to say and gives me all the time I need at my appointment. He is also there if you need him after hours. I am thankful to have him in my life. Doctors like him are special and hard to find.
I knew being an MDVIP Doctor would be the right thing for you and your patiences .It's a pleasure to go into your waiting room now and get to see you right away. You have a way of getting to the problem relatively quick
