I just messaged you. But if anyone stumbles on to this who is also interested in PHAP and has questions feel free to hit me up. I just "graduated" with the 2015 class and was heavily involved with the program's Executive Board. I ultimately chose not to accept a conversion position with CDC, but had a great experience in the program and am still fond of my time with the agency.
A few brief points to consider:
For me PHAP was a great experience and set me up perfectly to pursue my overall career goals in public health. I didn't always love my assignment or working as a field assignee, but the program gave me opportunities I absolutely would not have had otherwise. If you're on the fence, but can swing the moving expenses go for it!
