How We Deliver the Partial Hospitalization Program at Our La Mesa Center
Daytime programming at our La Mesa center runs in two blocks, morning and early afternoon, built around group work rather than a single therapist's office. Clients rotate through process groups, psychoeducation, and skills training such as DBT, with individual therapy and psychiatric visits layered in through the week. A small clinician-to-client ratio keeps each group manageable enough that shifts in someone's presentation get caught quickly. When symptoms settle, the same clinicians carry a client into IOP rather than handing the case off.

Medi-Cal is California's Medicaid program; in San Diego County it pays for this care as a Specialty Mental Health Service under County Contract 575462.
