I think that you just must have just gotten Laurie at a very bad moment, because in real life she is just about the nicest person in the world. I can say quite confidently that whatever your interaction was, it is not a reflection on the level of support or helpfulness you will find here at Cincinnati.
In general, every school gets a lot of calls asking for information, etc and it is always possible to catch someone at the wrong time. In this process overall, my advice would be to take any imperfect interaction you have with a grain of salt. At an interview I think that you will find the current students in any program more than willing to talk to you about how happy they are with the administration/level of support, and that is a much better gage than any phone conversation you have with the office staff.
First interview weekend here at Cinci isn't until December sometime, and most of the interview dates are in '09... so sit tight, you'll hear.
