I got referred to a physio once I had DD1, and then continued to see her - my hip had popped out and rotated so that made my pain worse, so it was probably best I saw a physio anyway.

Then I moved states and I went to a physio and he said he didn't believe SPD existed (I'm sure you can imagine what I thought of him) so I went and found a chiro who did believe it was a problem and she was great. I found women more sympathetic towards the problem than any male.

So no, I didn't have any specific reason for choosing them, it was just the way it went. I do think some care providers are better than others. Whereabouts are you located? maybe someone in here can refer a good person.
