Dear _________,
Congratulations on a suburb job of organizing our year-end formal dinner. When I asked you to head up the committee this year, I knew you were the absolute perfect choice. With your great organizational skills and meticulous attention to detail, from start to finish the event was flawless, and the feedback I’ve gotten from the partners is glowing. I sincerely thank you for a job well done. It was a first-class affair.
