Dear Dr. Horton,

I wanted to thank you for the care you and your staff have given me during the whole process of this elective surgery. Everyone has been kind and attentive, knowledgeable and patient. You have been honest, thorough and direct with me about what to expect and when. I cannot begin to tell you how wonderful and rare that is. I wish all my doctors were as tuned in as you are and I wish they ran their practices with both the warmth and efficiency that yours is ran with. I have felt both calm and certain about my decision to do this surgery. I have known what to expect at any given point. While I know I am still at the beginning of the healing process, I am delighted by the results thus far and I know it will only improve with time as I heal. You clearly love your work, are confident in your skill and I truly value that.

I will also add that Fernando and the staff at CPMC- Davies Campus were excellent and caring. They all spoke very highly of you. I am grateful and happy with all the care provided across the board by you and your awesome staff.

Thank you so much.
