Dear Dr Bartels,
Last year at this time I was getting my personal affairs in order as I prepared myself for surgery. You were going to remove an acoustic neuroma from behind my left ear. Through our conversations I was aware of the possible side effects of the surgery. It was, needless to say, a very difficult time in my life. I wish to express to you my gratitude for your remarkable skill and talent with which you performed my surgery, and the kind and meticulous follow-up care that I received from you and your office staff. There is honestly not a day that goes by that I don't think of you and say "thank you" and "God bless you." Words can never express my true appreciation for having a surgeon as eminently capable as you.
May you and your family have a healthy and happy holiday season.
