Top Law Schools

I am interested in going to law school to pursue a career working with indigent populations. As of now I am equally interested in handling civil cases (TANF, housing, family law, etc.) for a legal services organization or working at a PD office.

Suppose I landed a job as a PD. Could I ever exit that to work in a civil division of Legal Aid? Or vice versa?

I am asking because I figured I would go to law school and cast a wide net, participating in clinics and interning/summering with a variety of organizations serving low income populations, and ultimately apply to legal aid/legal services offices, PD offices, Equal Justice Works and school/firm sponsored pro bono fellowships. I just want to know how my first job would likely define the rest of my career.

Yes. Moving from criminal to civil is done seamlessly. And employers would not care, especially if you have substantial trial experience.
