The spouse & I were going to a large clinic/hospital for 40+ years, with about any specialist you could name, usually more than one or two. The hospital website had a photo, the list of their education and places worked, a description of how they specialized within their specialty, and an intro written by the Doc. None of them were right out of med school. They know each other in a hospital like that, so we felt comfortable with the referrals. If the Doc found you needed a different doc within her specialty, that's were she sent you. Weren't compatible with that one? Ask the clerk for a different one for the next appointment. Been there, done that, very recently. If the Doc doing the referral acted uncomfortable, maybe they were trying to tell you something.
Not everyone has that kind of facility available to them, but if you do, consider it.
Right now, our local hospital is having staff turnover like you wouldn't believe, for several years. That's a bad sign - something is wrong with the people in charge. That's a harder one to judge from the outside - unless it's your docs leaving constantly. Doctors/nurses can get a job somewhere else. It's not like there isn't openings.
On line, there are sites for medical professionals. One article that blew me away was entitled "the 10 worst states to work as a nurse". Holy Toledo. Those state get less applications and have a harder time keeping the ones they do get. Try the "scrubs" website, watch those links on the side of the page. I haven't been there since my cancer, a number of years back. Another site is for nurses - and some of them vent, there. You will learn a lot. They don't name names, but still....
No Doc gets 100% approval with public, but word-of-mouth is not a bad way to pick one - at least for the first appointment. Even better, find the support group for incontinence. Even check with the local hospital or Doctor - they often know about those groups and when and where they meet. Boy, will you get an earful at a meeting like that, good and bad! Mine had about 15-20 members, but it was great - worth attending once a month. Find someone you like, get them off to one side.
It's can be like: Do you want to talk to the boss/doctor, or the secretary/nurse who really knows what's gong on.
