^^^^pretty much that
From my own personal experience, in trying to find someone to rehab my severely foundered horse, the two most highly recommended AND qualified were the two that nearly killed him and I mean "killed" literally.
The Pete Ramey guy did a great job on my other three, the Ric Redden-schooled guy only worked on my foundered horse.
Had the foundered horse not been in the mix, I would have thought both these guys were the best thing since a slice of home made coconut cream pie at the local diner where I grew up. As it were, their "Legends in the Own Minds" selves, went about things THEIR way, which were both wrong and everybody, including the vet (and his X-rays), wasn't sure this horse would make it. He is finally on his way to a good recovery.
The best person to trim my horses is me but my back won't let me do that anymore, so the next best are two brothers with very little formal schooling, ten years experience, a lot of work ethic and common sense, and by gosh they listened to the vet regarding how to initially trim the foundered horse.
If you don't have a horse with special hoof needs, you shouldn't have problems finding someone.
If you do have a horse with special hoof needs, you will find out just how smart 90% of these great farriers and trimmers are not.
That was the best "yes, I guess not" answer I can give. If you don't like what the first person does, immediately start the hunt for someone else; don't wait until the horse needs trimmed again.
I wish you the very best in finding someone for the needs of your horse
