Which Level of Care Do You Need

The counts below reflect the 5 Walnut Creek facilities listed in this directory, weighted toward the higher levels of care.

Medically Supervised Detox

Detox manages withdrawal under clinical observation, usually across several days, and is where treatment begins for anyone physically dependent on alcohol, opioids or benzodiazepines. Around 2 of the 5 Walnut Creek facilities offer detox, with 1 more offering hospital inpatient care.

Inpatient Residential Treatment

Residential care provides a structured live-in setting for weeks or months. About 3 of the 5 Walnut Creek facilities offer it — three fifths of local provision, proportionally among the strongest in the Bay Area.

Outpatient, IOP and PHP Treatment

Outpatient care lets you live at home while attending sessions. Around 3 facilities offer outpatient services, 1 offers PHP and 1 offers IOP. Detox, residential, PHP, IOP and outpatient are all represented locally, which very few cities this size manage.
