I am not sure what your goal is with a JD/PsyD, but I will just say - be warned on the costs! I have been working as an attorney at large law firms for almost 5 years. I make a lot of money, a ton of money actually - and that is not meant to impress. I am not happy and haven't been since or during law school actually.
Alot of attorneys and PsyDs (I imagine) go to private schools like DU and find themselves behind the 8 ball. First, to get a good law firm job, you need your program to be ranked highly. Second, if you go to a private school, you are going to have a lot of debt, a LOT. Adding a PsyD to that unless it's funded, seems nightmarish. Think about the point of getting a JD and PsyD? What is the goal? I don't have a joint degree - just a law degree. I know the PsyD wouldn't help in law, maybe family law, but you don't need it to be an attorney. I assume you are thinking forensic psychology. You don't need a law degree to do this. You need the experience. Maybe a JD/PsyD would impress to be an expert witness. I don't know.
I am thinking about PsyD/PhD, but I don't want to use my law degree really. If I did and it made sense, great, but I am not looking for that.
I also went to a top-ranked state school and graduated with very little debt. I paid it off in the first year of working. I cannot imagine having a ton of debt on top of not liking what I did. I had a friend that went to University of Denver, she graduated top 3 in her class with a ton of debt, she was able to get a job at my firm because she was so high in her class - then they fired her in a bunch of layoffs. She didn't like being a lawyer anyway, but it was a smack in the face and she has an incredible debt load. Tough world out there right now.
I think you really need to do the math and think about your goals. The math can work in law, but the happiness factor might not. Maybe you can do a google search for some JD/PsyDs and see if you could that with him/her.
