My wife is a PT in NC and absolutely loves it. She has been a PT almost 8 years and has worked at hospitals, private practices and done home health. When applying for grad school she did not have a 4.0 (high 3s) but did have something like 2,000 volunteer hours at PT clinics, so she pretty much had experience that few others already had. It is a wonderful profession to get into with good salary, sign on bonuses, travel expenses, career advancement etc. and I would encourage anyone that is interested to go for it!
I am not sure about the "harder to get into than MD school" but I know it was harder than I thought it would be. I think she went to at least 3 narrow down interviews (160 applicants down to 80 down to 40 etc). She has her masters from UNC Chapel Hill and at that time it was one of the top ranked PT schools in the nation. She is considering getting her DPT but it would be hard with two small children, so we will see.
Just do us all a favor and be one of the PTs who actually cares if the patient gets better or not. Since my wife has become a PT we have seen/met so many who just go through the paces or treat every patient the same way (I know every profession has these people it just really bothers us to see it so often).
Just a PT spouse's take.
