Coastal Comprehensive Treatment Center — Wilmington, Los Angeles County

Coastal Comprehensive Treatment Center at 117 East Harry Bridges Boulevard in Wilmington is a flagship opioid treatment program (OTP) operated by Transcultural Health Development, Inc. As an OTP, Coastal Comprehensive dispenses methadone and/or buprenorphine for medication-assisted treatment of opioid use disorder — a distinctive regulatory category with federal DEA/SAMHSA oversight beyond state DHCS licensure. Meets our four-signal flagship bar: DHCS license, SAMHSA 2025 match, CARF accreditation for Outpatient Treatment (OTP) and Detoxification – Outpatient, and multi-LOC framing via the two CARF-accredited programs.

What makes this facility flagship tier

Our flagship tier requires four independent verification signals. Coastal Comprehensive Treatment Center clears all four.

DHCS license: active at the time of our most recent review. License number 190511CP, expiration 3/31/2027. Program authorization: outpatient treatment (non-detox).

CARF SUD-specific accreditation: see dedicated section below for specific program details.

SAMHSA 2025 National Directory: matched.

Multi-level of care: evaluated against the operator’s program scope, whether across DHCS program codes, CARF-accredited programs, or co-located operator sites.

Clinical program overview

As a federally regulated OTP, Coastal Comprehensive provides medication-assisted treatment (MAT) — methadone maintenance, buprenorphine prescribing, naltrexone access — combined with counseling and psychosocial support required by SAMHSA OTP regulations. CARF’s Outpatient Treatment (OTP) accreditation indicates the specific OTP-regulatory compliance and clinical programming standard. Detoxification – Outpatient accreditation reflects medically supervised outpatient withdrawal capacity.

Who this facility is a good fit for

Coastal Comprehensive serves patients with opioid use disorder (OUD) requiring MAT — methadone, buprenorphine, or naltrexone maintenance. Patient populations span Medi-Cal DMC-ODS contracted, commercial-insurance covered, and patients accessing OTP care through specific OUD treatment pathways. Not a residential facility — no beds; outpatient MAT delivery only. OTP regulation requires daily or near-daily dosing for new methadone patients, with take-home privileges earned over time.

Location and geography

117 East Harry Bridges Boulevard in Wilmington serves the South Bay and Harbor-area populations. Methadone OTPs historically concentrate in urban geographies where OUD prevalence is high and federal regulatory oversight can be operationally maintained. Our opioid addiction pillar covers the OUD clinical framework and MAT options in SoCal context.

CARF accreditation

Coastal Comprehensive Treatment Center holds current CARF International accreditation for SUD-specific programming — specifically: Detoxification - Outpatient, Outpatient Treatment (OTP). CARF accreditation is a voluntary third-party clinical quality review covering program design, clinical outcomes measurement, health and safety, governance, and continuous improvement. It is not a regulatory requirement for California SUD treatment operation but signals operator investment in an independent quality-assurance process that many DHCS-licensed facilities do not pursue.

Families evaluating Coastal Comprehensive Treatment Center can confirm current CARF accreditation status and program scope directly at the CARF provider search.

DHCS licensure detail

Coastal Comprehensive Treatment Center operates under DHCS certification 190511CP (Certified), authorized for outpatient treatment (non-detox). DHCS records do not list a residential bed capacity (consistent with an outpatient-only or day-program authorization). The license is current through 3/31/2027.

DHCS enforcement records should be checked for any specific facility before admission. Our DHCS license verification walkthrough provides the tool-based methodology.

SAMHSA National Directory

Coastal Comprehensive Treatment Center appears in the SAMHSA 2025 National Directory of Drug and Alcohol Abuse Treatment Facilities, providing cross-source verification from a federal registry independent of both CARF and DHCS. SAMHSA directory presence is one of the four independent verification signals our flagship tier requires.
