Wellness Facilitator

Elizabeth is a licensed psychiatric mental health nurse practitioner whose experience is grounded in treating people with substance use disorders.

Belinda brings years of experience as a counselor in the field of chemical dependency and recovery. She has a Bachelor of Arts in Interdisciplinary Studies: Arts and Human Sciences from Marylhurst University and a Masters of Divinity from Naropa University.
