Dear Dr. Kim, words cannot adequately express the depth of my gratitude for the amazing work you did during my emergency back surgery. Thanks to you and your heroic efforts, my ability to walk- which was deteriorating rapidly at the time- is slowly returning. In addition to your remarkable surgical skills, Kathryn and I have also greatly appreciated the frequency of your visits while I was in the hospital last month, your wonderfully easy going nature, and your willingness to discuss all aspects of my case with us- including the breath-taking challenges with the type of surgery that you performed on me. For all these reasons, you will always have our eternal gratitude. Keep up the excellent work!
