Volunteer Program 2025


The College of Naturopaths of Ontario (CoNO) relies on the contribution from our volunteers to ensure the success of various programs that support in the effective regulation of naturopathic care in Ontario. In this In Conversation With (ICW) session, the College provided an in-depth look at its Volunteer Program and the benefits it offered to our volunteers, including:

  • Gaining valuable experience and insights into the regulatory process.
  • Building professional networks within the naturopathic community.

This session featured a panel of current volunteers who shared their experiences on various committees and in the field, providing real life examples of what it was like to volunteer with CoNO.

Whether you were a registrant, or a member of the public, the session presented an excellent opportunity to learn more about how you can contribute, grow professionally, and be part of a dynamic community.
