I am writing a thank you note to an asst director of a department at the hospital where I will hopefully find employment when I graduate. She helped me gather information for a community project that I am doing in school.
But ... here's the question ... I don't know how to address her in the letter. I don't know if she is a Mrs. or a Miss. Is it appropriate to use Ms. if you don't know?
Seems like a silly question, but I want to make a good impression!
