a stupid question about a follow-up

<p>This question is probably going to sound stupid and nit-picky, but I'll pose it anyways. So a couple of weeks ago I had an interview with the Director of College Admissions of USC. I'll be writing a follow-up letter to her; however, I don't know how I should address the note. She introduced herself simply by her first name, but she gave me her card so I could just as easily write a "Dear Ms (last name)" as I could do a "Dear (first name)." Of course, using the last name sends me into the tricky situation of addressing her as Ms. or Mrs. or Miss. Would using her first name sound personable or unprofessional?</p>

<p>I actually had the same problem a few months ago! Even though my interviewer addressed herself with her first name, I felt like it would be too unprofessional to call her that. So i just did Ms. (Last name). I guess I wasn't much help since I don't know the answer, but that's what I did in that situation.</p>

<p>Use Ms....</p>

<p>Look on the college web site and see if she has a doctorate because if she does, then, you also could address her as Dear Dr. [insert last name here]"</p>

<p>What's most important, however, is sending the letter, which will make you stand out because most interviewed students don't bother with that courtesy.</p>

<p>Thanks for the advice!</p>
