Dr. Lori Regenstreif

OCFP Programs: Peer Connect

Clinical Interest: Addiction Medicine


Dr. Regenstreif has had a focused practice in addiction medicine since 2011.

She started by prescribing methadone and buprenorphine for Opioid Use Disorder in Hamilton, then spent a year in New South Wales Australia, working with the Hunter New England Drug and Alcohol Clinical Service. She returned to Ontario in 2014 and completed an MScCH in Addiction and Mental Health at the Dalla Lana School of Public Health.

These experiences, together with the inspiration from many mentors, prompted her to get more involved in research, and to start comprehensive addiction care programs such as a RAAM clinic and an in-patient addiction medicine service in Hamilton.

Dr. Regenstreif has devoted much time and effort to mentoring physician and nurse practitioner colleagues in the Shelter Health Network and in the detention centres to promote the use of Opioid Agonist Therapy (OAT) in community and prison settings. She works in a youth detention centre in Hamilton, as well as several out-patient settings and the hospital system.
