I appreciate your expertise and insight into what (Insert college) has to offer its students. As a result of our conversation, I am even more eager to become a member of the Class of (Insert year).

Sending a thank you note distinguishes you from other candidates. Not only does it remind the recipients of who you are, but it makes them feel good about what they do and why they do it!
