Care offered

From the program's public listing:

  • Detox: medical help to get through withdrawal safely.Ask how long people usually stay, whether a nurse or a doctor is there overnight, and what happens on the last day. Detox on its own is not treatment for addiction, so ask what this program offers afterwards and whether a place is held while someone finishes.
  • Residential: live at the program and take part in treatment every day.Ask how long a stay usually runs, what a day looks like, what someone may bring and when family can visit. Ask what happens if a resident needs medical care, and what the program sets up before anyone leaves.
  • Outpatient: regular visits, such as counseling, therapy or medication appointments.Ask how soon a first appointment can happen, how often visits come after that, whether the same clinician is kept each time, and whether they will see someone who is still drinking or using while they get started.
  • Medication for addiction (MAT): medicines for opioid or alcohol use disorder, used with counseling.Ask which of buprenorphine, methadone and naltrexone they can prescribe, whether a prescriber is on site, whether they will carry on a medication someone already takes, and whether counseling is required to keep the prescription.
    • Prescribes medication for opioid use disorder
    • Prescribes medication for alcohol use disorder
  • Licensed Primary Mental Health Care
