There is no "fast" way to become a licensed physical therapist--in any state. The quickest way would have been to attend a university that offers a 3+3 program. However, since your about to finish your bachelors...
Anyway, there are still a few programs in CA that offer the Masters of Physical Therapy degree. Even then, many, if not all, of the programs are STILL 2.5-3 years long. There's no getting out of it. I would check apta.org concerning the programs available to you in CA.
As stated in many threads here, the PT curriculum is very rigid and structured. You take the classes when the program tells you to take classes. I don't believe there are any accelerated programs out there that will award a DPT degree in less than 2.5 years.
