About

About Diablo Valley Drug and Alcohol Services

Diablo Valley Drug and Alcohol Services is an inpatient and outpatient addiction treatment center with locations in San Ramon and Walnut Creek, California, serving the broader San Francisco East Bay region. The facility is licensed by the California State Department of Health Care Services and operates under the clinical direction of Daniel Smeester, MD, who brings more than 20 years of experience and dual board certification from the American Board of Addiction Medicine and the American Board of Emergency Medicine — a combination that positions the center to manage complex withdrawal cases alongside co-occurring medical and psychiatric conditions.

The center’s levels of care span the full treatment spectrum. Inpatient Medical Detox sits at the most intensive end, providing medically supervised withdrawal management for patients requiring close clinical monitoring. From there, patients can step down to Residential Inpatient programming lasting up to 30 days, followed by a Partial Hospitalization Program (PHP), an Intensive Outpatient Program (IOP), or standard Outpatient services — allowing for structured transitions at each stage of treatment.

Treatment at Diablo Valley incorporates Medication-Assisted Treatment (MAT) alongside individual counseling, group therapy, and family counseling. The center addresses substance abuse, opioid addiction, and alcohol dependency, as well as co-occurring disorders including depression, anxiety, and chronic pain — conditions that frequently complicate withdrawal and early recovery.

Diablo Valley Drug and Alcohol Services is built for patients and families across Contra Costa County who need a medically credentialed detox program close to home. The combination of an on-site physician certified in Addiction Medicine, a full continuum from inpatient medical detox through outpatient care, and treatment for co-occurring disorders makes this center a substantive option for those facing the medical risks of withdrawal.

  • Medical director holds dual board certification in Addiction Medicine and Emergency Medicine — directly relevant for patients managing medically complex withdrawal
  • Inpatient Medical Detox with Medication-Assisted Treatment (MAT) available under physician supervision
  • Full continuum of care: Inpatient Medical Detox → Residential → PHP → IOP → Outpatient, reducing the need to transfer facilities
  • Treats co-occurring disorders including depression, anxiety, and chronic pain alongside substance use — critical for patients with dual diagnoses
  • Licensed by the California State Department of Health Care Services, serving San Ramon, Walnut Creek, and the broader San Francisco East Bay

Inpatient Medical Detox in San Ramon and Walnut Creek

Diablo Valley Drug and Alcohol Services provides Inpatient Medical Detox for individuals who require clinical supervision during withdrawal. The program operates under the oversight of Daniel Smeester, MD, whose certifications from the American Board of Addiction Medicine and the American Board of Emergency Medicine reflect the level of medical acuity the center is equipped to handle. For patients and families weighing detox options in Contra Costa County, that clinical background is a meaningful distinction.

Medication-Assisted Treatment (MAT) is integrated into the detox and treatment process. The facility is licensed by the California State Department of Health Care Services and treats opioid addiction, alcohol dependency, and substance abuse, including patients presenting with co-occurring conditions such as depression, anxiety, or chronic pain that can complicate withdrawal management.

Continuum of Care: From Medical Detox to Outpatient Treatment

One of the structural advantages of Diablo Valley Drug and Alcohol Services is the ability to move patients through multiple levels of care within a single provider system. After completing Inpatient Medical Detox, patients can transition to Residential Inpatient programming — which runs up to 30 days — before stepping down to a Partial Hospitalization Program (PHP) or Intensive Outpatient Program (IOP).

This step-down model matters for patients whose withdrawal and early stabilization require consistent clinical relationships rather than handoffs between unconnected facilities. Outpatient services are also available for patients who do not require residential placement or who are continuing treatment after a higher level of care.

Co-Occurring Disorders and Withdrawal Management

Detox and withdrawal management are rarely straightforward for patients who also live with depression, anxiety, or chronic pain. Diablo Valley Drug and Alcohol Services lists all three among its confirmed conditions treated, alongside substance abuse, opioid addiction, alcohol dependency, and co-occurring disorders broadly defined. Addressing these conditions during and after detox is integral to the center's treatment approach.

Individual counseling, group therapy, and family counseling are among the therapeutic methods in use at the facility. For families in the San Francisco East Bay navigating a loved one's crisis, the presence of family counseling within the same program — rather than as a separate referral — allows for more coordinated support during the detox and residential phases.

Serving Contra Costa County and the San Francisco East Bay

Diablo Valley Drug and Alcohol Services operates out of San Ramon and Walnut Creek, two Contra Costa County cities well-positioned to serve patients from across the San Francisco East Bay. The center's primary service area includes San Ramon, Walnut Creek, and the surrounding region, providing a locally accessible option for medically supervised detox and inpatient addiction treatment.

The facility's administrative offices are open Monday through Friday, 9 AM to 5 PM. Prospective patients and family members can reach the center directly at (925) 289-1430 to discuss admission and program options.
