Aaron Van Gaver, N.D.

Dr. Aaron Van Gaver has been practicing as a naturopathic physician for 17 years and an addiction counsellor for the past 8 years. Through his own personal journey in overcoming addiction, he was motivated to help others who struggle with this disease and to educate and empower other naturopathic doctors to help our patients - many of whom grapple with addiction every day. Learning the tools and skills that are needed to create a safe and healing space for patients has been the cornerstone of Dr. Aaron's naturopathic practice. By talking about addiction, he endeavors to eliminate the stigma that exists surrounding addiction and mental health, so that so many of our patients (and those of us doctors that share in this struggle), feel comfortable to reach out and ask for help.
