Dear Dr. Horwath,
I would like to sincerely thank you for your wonderful treatment yesterday. I haven't felt or looked this fresh and rested in a long time!
You really have almost worked a miracle. My face looks more natural again, my eyes are more open, and overall I'm simply happy again!
Many, many thanks for making the appointment possible even so close to my vacation.
In short: It was a great success and I am utterly impressed by your skill!
With warm regards!
