About Open ARMMS Inc
Open ARMMS Inc occupies the Waldorf location of Addiction Treatment Systems (ATS), a network of six methadone and Suboxone clinics across Maryland and West Virginia that has provided medication-assisted treatment to the community for more than 25 years. Operating from 2590 Business Park Court in Waldorf — in Charles County, southern Maryland — the clinic is CARF accredited and SAMHSA-certified as an Opioid Treatment Program.
The clinical model is straightforward and proven: daily methadone or buprenorphine (Suboxone) dispensing, paired with structured individual counseling, group counseling and family counseling. The clinic emphasizes same-day admissions Monday through Friday, welcoming walk-ins and offering same-day medication when patients meet admission criteria. This walk-in access is a critical feature for patients in active opioid use who cannot afford the typical multi-week wait at less-accessible programs.
Open ARMMS specifically serves adults with opioid use disorder, including pregnant women — a population requiring specialized dosing and obstetric coordination. The clinic also addresses co-occurring mental health conditions through its counseling track, with referrals to outside psychiatric and primary-care providers where indicated. Patient testimonials repeatedly highlight the Waldorf program director and counseling staff for their accessibility and personal investment in patient outcomes.
Payment options span Medicaid, Medicare, private insurance, state-funded coverage and self-pay. ATS’s broader mission is to make opioid treatment affordable and accessible, and the network publishes its commitment to serving the community without discrimination based on sex, race, class or culture. Patients can reach Open ARMMS at (301) 645-5538 or simply walk in to schedule an intake during weekday business hours.
