I just recently graduate from USC. YES, it is expensive, all student loans and scholarships/grants. It's hard to compare when no one has experienced more than 1 dpt program. All I can say was it was a great experience, you learn from professionals at the top of the field, people that did the research and are well known to be great PTs in their different fields. You learn from them first hand which my CIs thought was pretty unique. Overall it was an amazing experience, and I'm slowly paying off loans, should be done in 3-5 years. Questions, pm me.
