    He did not take his time with me, didn't let me tell him about my body what is going on with me,just listen to my breathing and left the room, didn't like that at all, I want a doctor to listen to me that's why I am there.

    He’s been my doctor since I was in Diapers. I wouldn’t have another doctor care for me. He listens to me whine, cry & he always shakes my hand =). Best doctor ever & refers me to great care if it’s something he can’t handle. Thank you Dr. Kozarek!! He’s Family even though not by blood.
