Portland Community College
Portland Community College (PCC)'s HT Program prepares students for the Horticultural Therapist-Registered (HTR) designation with the American Horticultural Therapy Association, and provides students not yet meeting the AHTA HTR requirements the opportunity to develop the knowledge and skills to work as therapeutic horticulture activity specialists with diverse populations in a variety of settings.
The Horticultural Therapy Program began in 2008 in collaboration with Legacy Health’s Therapeutic Gardens and Horticultural Therapy Program, led and inspired by Teresia Hazen, who taught the core horticultural therapy courses and supervised internships in Legacy’s 14 therapy gardens. In the Winter 2018 term, the HT program was transplanted to the PCC Sylvania Campus. Legacy Health is still a leader in the community, offering internships and therapeutic gardens for all the enjoy.
