NFT: Physical therapy question

If there are any physical therapists out there my question is this. How can you tell the difference if someone is a good therapist and really knows their craft as opposed to one who appears to say and do all the right things and simply follows the script.

I'm a distance runner with a neck and shoulder problem that eventually landed me a cortisone shot. The therapist I was seeing I thought she was doing a good job but lingering symptoms have remnained and seem to have developed into a new problem.

I also had a groin issue that the same orthopedic sent me for therapy but with a different therapist. This therapist seemed to be on the right track and had some concerns so she consulted another who had more insight into what she felt was the problem. Wow. In a two day period there is no question my groin issue is soon going to be no issue at all.

I felt this girl really seemed to have more depth in what she was doing and I started to tell her about my shoulder and neck issue which she kind of hinted at she might take a look at once we get the leg going in the right direction. Both therapists work at the same facility and I don't want to cause a rift. But I am feeling like I have a lot more confidence in this therapist then the other.
