The Horticultural Therapy Certificate is now an accelerated hybrid program

Horticultural Therapy Certificate program, accredited by the American Horticultural Therapy Association, provides students with a hands-on opportunity to learn the knowledge and skills required to work in social, therapeutic and vocational horticultural settings. Students study the theory and history of horticultural therapy, and gain experience developing treatment plans and therapeutic activities for a variety of client populations, as well as how best to engage clients in therapeutic activities. Students will learn about designing facilities for special populations and getting started in establishing and managing a horticultural therapy practice.

Job opportunities can be found in hospitals, nursing homes, assisted living facilities, rehabilitation centers, correctional facilities, schools and community gardens. With additional general coursework and a supervised internship, graduates are able to apply for professional registration through the AHTA.

The certificate program starts every fall semester and can be completed in three consecutive semesters of part-time evening study.
