What does that mean? You can start with years of experience and amount of training. Doctorate level therapists (psychologists) have a lot more training and more rigorous path to being licensed than masters level therapists. That said, even if they're doctorates, you might have to look at the program they went through as well. Overall, your chances of getting a good therapist are higher if they have a good amount of years' experience and are psychologists (doctorates). As an additional note, some like the idea of seeing a psychiatrist but many times they're not great therapists because that's not their only/main focus.

Another thing to look at is the type of therapy offered. Look into different types and see what might be a good fit, but it's possible that the best fit isn't the one you're most comfortable with.

All that said, the best therapist in the world can't work with someone who's unwilling to work. You have to be willing to do the work. If you're not, you're just wasting your money and the therapist's time. Figure that out first if you have to.

Finally, coaching is not therapy (not even close). Make sure someone is actually licensed if they claim to be a therapist. Usually you can do that through Psychology Today.
