Dear Ms. Joseph:
Thank you so much for taking time from your busy schedule to answer my questions about possible careers in gerontology. You gave me a wealth of information that I could never get from a course or book. I certainly appreciated your advice and look forward to meeting with Mr. Elton and Ms. Whitely, as you recommended.
Meanwhile, I will keep you informed of the progress in my career search.
Yours sincerely,
Sarah Brown
