from Cheryl in NY March 1, 2018 for John P. O'Connor, MD

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.
