I'm very anxious about an upcoming surgery. As I was leaving Dr. Sanger handed me 2 cards with scripture verses on them. They sure were fitting and helped me.

Highly recommend both the nurse and Dr. Sanger. Both asked if there was anything else we needed besides the reason we came in. Never felt rushed even though we had gotten squeezed in to be seen that day.
