Dear Dr. Singerman and Staff,
Just a note to express my heart-felt thanks & appreciation for you “fixing” my eye and restoring my clear vision. I would be remiss not to compliment your team on their professionalism, expertise, and their sincere kindness—this was true from the receptionist desk all the way to setting up the follow-up appointment. Frankly, your team is the best group of folks I’ve encountered (since I left [my team]).
Take good care, Jeff
