Frequently asked questions
Who will be involved in my care?
Your care arrangements depend on the program and your assessed needs. Ask admissions how your care team is arranged when discussing the Inpatient Residential Program, Medical Detox Program or Virtual Outpatient Program. A directory listing does not guarantee assignment to a particular professional.
Who decides whether I need detox?
Whether you need detox, and its anticipated duration, are determined at your medical intake assessment with our nurse and doctor. Our intake coordinator can explain the admissions process and help with practical arrangements.
How can my family ask about support?
Explore the Family Support Program or send an Admissions Enquiry. Our intake coordinator will follow up by phone or email. You can also request a visit using Book A Tour.
