Opinion: Is it appropriate to give your physician a personal gift?

Dear Dr. Roach: We are very fond of our family doctor. I was in to see him the other day, and it came up in conversation that he was going to be getting married this summer. We would like to acknowledge this event in his life with either a lovely card or a small gift. I know the old-school way of thinking is to never do things that are so personal when it comes to your physician. Do you think that still holds true today? – N.W.
