Dear [ ]
I was sorry to receive your letter explaining your recent health problems, as well as your notice of resignation from [company’s] board of directors. I will hope for a full recovery.
Thank you for your valuable service on the board, [your promotion of our strategic plan, and your knowledgeable contributions related to the global marketplace]. [Company] certainly would not have progressed so far in the last [two years] without your efforts.
You will continue to receive our company newsletter and, of course, the annual report. I hope you will contact us occasionally to let us know how you are doing.
Best wishes,
