Dear Dr. Holbrook:
Thank you for the superb job you have done restoring my upper teeth. Not only am I no longer embarrassed to smile, I now feel confident smiling broadly and showing my new dental work. While you were generous in crediting the dental lab with the outcome, I know very well that the lab staff would not have been able to do their job without your having done yours so expertly. Furthermore, it has been a pleasure being around you and your staff. It is obvious that you all enjoy your work and take a great deal of pride in it.
Please accept my sincere thanks for the outstanding job. It would have been remiss of me not to let you know how thrilled I am with the results of the work you have done. Feel free to use this as an unsolicited endorsement of your practice, and be assured I will not hesitate to recommend you as the occasion arises.
