My guess would be that you can get a Master's in Mental Health Counseling in order to get a Ph.D. in Clinical Psychology.
I would try to talk with someone at the schools you're considering to figure out what degrees their current students have.
From what I've heard the Ph. D. is more research oriented versus the Psy. D.
It can all be very confusing.

I hope the link helps. I just did a quick search on Yahoo! for "Psy. D." and that was one of the first links to come up.
