No state-level location landing pages for California - every other state served has one, the primary market does not
You serve clients in California, Colorado, Maryland, Pennsylvania, and Virginia. You have location pages for Colorado (/locations/colorado/), Maryland, Pennsylvania, and Virginia - but nothing for California, where your practice is headquartered and where the majority of your team is based. Someone in California searching 'therapist in California accepting new patients' or 'psychologist Woodland Hills' has no dedicated page to land on. Local searches in your biggest market are being missed entirely.
Recommended action
Create /locations/california/ as a hub page listing your California-based therapists, in-person locations (Woodland Hills, Encino, etc.), and the conditions you treat in that state. Then create city-level sub-pages for each physical office location (/locations/woodland-hills/, /locations/encino/) with address, Google Map embed, LocalBusiness schema, and a list of therapists at that office. Mirror the structure that exists for other states.
