Dear Dr. Lewis:

Enclosed please find a referral form from my primary doctor to cover the visit to your office on Friday, October 16.

I want to express my thanks to you and Bev for such outstanding service. You both treated me as if you had know me for years, which made me feel very comfortable during a time when I was not really feeling like myself.

Thanks again, and should you need anything further from my insurance company, please let me know.

Sincerely,

Susan
