"Dr. Wiener,
A brief note to say Thank you for your excellence, kindness, skill, and follow-up before, during, and after my surgery. I appreciated the time that you took in explaining the procedure and the reassurance you gave me. I was anxious about the surgery, however, you and your staff eased my mind greatly. Please say Thank you to your staff. Everyone there is always pleasant, courteous, and helpful. Please give a special thanks to Donna, she is definitely an asset to your office.
It has been my sincere pleasure in meeting you but must importantly thank you for helping to restore my self confidence through your work. In my opinion you are an excellent surgeon and a truly gifted man."

Thank you for answering all my questions. You're a great surgeon with a wonderful personality. There are many Doctors, but only few really care about their patients. You are one of the "few" chosen ones."
