I would ask him what are the various approaches to managing ADHD.

There are some therapists who specialize in ADHD and use behavioral approaches, group and individual therapy.

there are some providers who prescribe stimulant medication.

There are some providers who recommend changes in diet.

I would see what your PsyD says. Even if he recommends one approach over others, can he tell you about the other approaches? It is nice to know what the options are.

Good luck.
