Drug and Alcohol Rehabs in San Dimas, CA

San Dimas kept its Old West frontage on purpose. The city adopted a western architectural theme for its downtown in the 1970s, and the wooden facades along Bonita Avenue are the result.

It incorporated in 1960, and the name comes from San Dimas Canyon, named in turn for the penitent thief of the Gospel accounts.

Frank G. Bonelli Regional Park covers nearly two thousand acres around Puddingstone Reservoir on the southern edge, with Raging Waters beside it.

The Walnut Creek and San Dimas Canyon trails run into the Angeles National Forest above the city.

The 210, 57 and 10 all pass close, with La Verne east and Pomona southeast.

Los Angeles County recorded 2,298 accidental drug overdose and poisoning deaths in 2025, a 6 percent fall from the previous year and the third consecutive annual decline, according to the county Department of Public Health. Deaths are down nearly 30 percent from the 2022 peak of 3,220, driven by a more than 40 percent reduction in fentanyl-related deaths.

San Dimas carries a single listed treatment program, so most people here look toward Pomona or Claremont.

Which Level of Care Do You Need

Pomona, Claremont and La Verne all sit within fifteen minutes. Counts come from the federal SAMHSA treatment locator.

Medically Supervised Detox

Detox manages withdrawal under clinical observation across several days. None operate in San Dimas; around one hospital inpatient program sits in Claremont, with 122 detox programs across Los Angeles County.

Inpatient Residential Treatment

Residential care means living on site for weeks or months. Around three residential programs sit in Pomona and two in Claremont within fifteen minutes.

Outpatient, IOP and PHP Treatment

Outpatient care lets you keep working while attending sessions. The San Dimas program offers outpatient care, with four more in Claremont and two partial hospitalization programs there.

Dual Diagnosis and Co-Occurring Disorders Treatment

Dual diagnosis care treats a substance use disorder and a mental health condition together rather than one after the other. All four Claremont programs treat co-occurring serious mental illness, around fifteen minutes east.

Sober Living Homes and Transitional Living

Sober living homes provide substance-free housing after formal treatment ends. Certification of California recovery residences is by the California Consortium of Addiction Programs and Professionals rather than the state.
