Why Grata
Grata handles prescribing, monitoring, and ongoing addiction care so your patients get specialist-level treatment while staying with you for the rest of their health.

We specialize in opioid use disorder and alcohol use disorder. Our providers prescribe evidence-based medications including buprenorphine (Suboxone) for OUD and naltrexone for AUD, tailored to each patient's needs.
With patient consent, we provide regular clinical updates to your office including treatment notes, medication changes, and progress summaries. We can communicate via secure messaging, fax, or your preferred method.
