The HTI’s Horticultural Therapy Certificate

Training professionals in the core
knowledge of horticultural therapy

Based in Denver, Colorado, the Institute has reached students from nearly every state in the U.S. and across the globe through an intensive course format. Additionally, we have expanded to offer certificate courses in other parts of the U.S.

Unique course format:

  • Accommodates working adults and students
  • Requires minimal travel, with only four visits to the class site
  • Offers significant face-to-face instruction and interaction
  • Four or five day class meetings combined with pre and post-class assignments done at home.
  • Provides opportunities to capitalize on the breadth of experience of students and instructors
  • Allows certificate completion in one year.

HTI program objectives

The certificate program gives students the skills necessary to establish, manage and work in viable, effective HT programs.Through a curriculum based on recognized competencies, students experience practical problem-solving, as well as discussion of the “heart” of the human/nature connection. Students with diverse life experiences contribute to a rich forum of ideas throughout the courses and serve as a network of resources to enhance budding HT programs. The certificate programs offers:

  • Four courses designed to train professionals in the core knowledge of HT.
  • Classroom experiences combined with assignments and projects accomplished at a distance.
  • Classes and distance assignments that are practical, useful, real-world experiences — enabling students to gain proficiency and confidence to practice HT in their own communities.
  • High-quality educational opportunities with faculty members who are experienced and enthusiastic practitioners and educators.
  • AHTA accredited certificate program.
  • Optional Academic Credit from Colorado State University
