“Dr. McGann was warm, friendly & calming. He listened to my concerns about my dad, and made me feel at ease. He was kind to my dad who is starting to have some trouble remembering things, so he didn't mind repeating for him. It just felt like he genuinely cared for his well being. The staff were also very kind. A smile goes a long way and we got a smile from the time we walked in the door, to the nurses, and the ladies that check you out. When you start caring for an elderly parent, it's hard, but doctors and staff like this make it a little easier. Like, they're right there with you. I wish all his doctors were like this.
