Yup.
One generalist and one gender therapist when I was first getting therapy. I dropped the generalist after a couple of sessions with the gender therapist as my issues seemed to be entirely within her purview and the generalist was lacking in experience and training with transgender issues.
Currently, I see my gender therapist for individual and small group sessions, and another therapist for larger group sessions that tend to be focused a bit more on transition nuts and bolts related to the group's common provider, Kaiser NorCal. That's handy and a bit different, a "What to do/Who to call" sort of thing.
