PLEASE HELP!!!! In Biology I have a report and there are some certain questionsi need to ask.
: How much money do you make in the 1st year of work. then about how much do you get after about5 years? : What are some benefits of being a physical therapist? : What other careers would you be able to pursue with the schooling you already had.
: Is there a higher type position you could earn after being a physical therapist? : How long do you have to be an assistant to someone before being able to do things by yourself? Thanks so much
