Memorial Hermann Prevention and Recovery Center/Adult Program

Memorial Hermann Prevention and Recovery Center Adult Program — operating under the Memorial Hermann Health System banner — is a CARF-accredited substance use disorder treatment facility located at 1733 Woodstead Ct in The Woodlands, Texas. The center treats substance use disorder and co-occurring psychiatric conditions across a full continuum of care, with physician-led clinical oversight provided by Medical Director Mike Leath, M.D., and Director of Psychiatry Carlos Guerra Jr., M.D. That dual medical and psychiatric leadership distinguishes PARC from many standalone outpatient programs in the Montgomery County area.

The facility offers four distinct levels of care: detox, residential treatment, Partial Hospitalization (PHP), and Intensive Outpatient (IOP). This stepped-care model means patients can enter at the appropriate level of clinical intensity and transition through the continuum without changing providers — from initial detox through residential stabilization and into structured outpatient programming. Having detox on-site, backed by a credentialed Medical Director, allows the program to manage withdrawal before moving patients into longer-term therapeutic work.

Clinically, the program draws on 12-Step frameworks, measurement-based care, and relapse prevention planning — a structured combination that tracks treatment outcomes and builds long-term coping strategies. Co-occurring disorders are addressed alongside substance use, reflecting the dual medical and psychiatric staffing. After completing a primary treatment phase, patients have access to the Discovery for Life post-treatment program, as well as LGBTQ+-specific aftercare support and continued relapse prevention resources.

MHPARC serves a notably broad population: adults 25 and older, young adults 18–24, teens 13–17, professionals and executives, veterans and first responders, and LGBTQ+ individuals. Few facilities in the Houston metro area combine physician-led detox, CARF accreditation, and dedicated programming for this range of populations under one roof. For families or individuals weighing detox and residential options in Montgomery County, the center’s clinical depth and population-specific pathways make it a substantive option worth serious consideration.

Memorial Hermann Prevention and Recovery Center Adult Program operates a dedicated detox level of care, overseen by Medical Director Mike Leath, M.D. The presence of an on-site physician medical director — alongside Director of Psychiatry Carlos Guerra Jr., M.D. — means the detox program carries both medical and psychiatric support, a clinical combination that matters when managing withdrawal in patients who also present with co-occurring mental health conditions.

Detox at PARC feeds directly into the facility's residential program, allowing clinicians to transition stabilized patients into longer-term treatment without a gap in care or a change in provider team. For individuals and families evaluating detox centers in Montgomery County or the greater Houston area, that continuity across the care continuum is a practical advantage worth factoring into the decision.

PARC provides four levels of care under one program: detox, residential treatment, Partial Hospitalization (PHP), and Intensive Outpatient (IOP). This structure reflects a step-down model — patients can begin at the level that matches their clinical needs and move toward less intensive programming as they stabilize and build recovery skills. Not every treatment center in the region offers all four levels, which means patients sometimes have to transfer facilities mid-treatment.

The clinical team uses measurement-based care to track patient progress across these levels, pairing outcome tracking with 12-Step participation and structured relapse prevention work. Co-occurring psychiatric disorders are addressed throughout the continuum, supported by the Director of Psychiatry on staff. The program culminates in aftercare planning through the Discovery for Life post-treatment program, giving patients a structured path after completing primary treatment.

Memorial Hermann PARC serves adults 25 and older, young adults 18–24, and teens 13–17, and the program includes population-specific pathways for groups that often face barriers in standard treatment settings. Veterans and first responders, professionals and executives, and LGBTQ+ individuals are all listed as served populations — and the aftercare framework includes dedicated LGBTQ+ support, indicating that population-specific programming extends beyond intake into post-treatment continuity.

For families researching detox and residential options for a teenager, PARC's inclusion of teens 13–17 within a facility that also carries CARF accreditation and physician-level oversight is relatively uncommon among private substance use disorder programs. The breadth of populations served, combined with the stepped care model, positions PARC as one of the more clinically comprehensive options in Montgomery County.

PARC holds CARF accreditation — the Commission on Accreditation of Rehabilitation Facilities — which requires programs to meet rigorous standards for clinical quality, patient rights, and program outcomes. CARF status is independently verified and not self-reported, making it a meaningful marker when comparing detox and residential programs in the Houston metro area. The facility is also LegitScript certified, a credential relevant to programs operating in the digital advertising space.

Leadership includes CEO Anna Gaddy, Chief Clinical Officer Anselm Khoo (LPC-S, CCM, NCC, M.Ed.), Director of Clinical Services Traci Gauen (MA, LPC-S, LCDC), and the two physician-level leads noted above. That credentialed clinical leadership team — spanning licensed counselors, certified case managers, and physicians — reflects a program built around professional clinical accountability rather than peer-support alone.
