Dear Dr. Kahn: I would like to take this opportunity to thank you for care for me during the past months. After a variety of surgeries, I am much better and healthier than when I saw you first in your office. Your attention to my case and your dogged determination were commendable. Also, I would like to thank your staff, as well. They provided a good team for the mission at hand. I am aware that I will be under your care for continued monitoring of my condition and I look forward to thanking you in person. Meanwhile, please accept this as my expression of sincere gratitude and respect.
