We’re Celebrating 15 Years!

The Horticultural Therapy Institute will mark its 15-year anniversary in 2017. To a large extent, our success can be measured by the success and contributions of our students and graduates. We want to thank all of our students, graduates, faculty, volunteers, partners and donors for your continued support over the years. While we are proud that the field of horticultural therapy and HTI have made great strides in this time, much still needs to be done. To that end and as part of HTI’s ongoing educational efforts, we have joined the ColoradoGives Program to help raise funds for horticultural therapy training programs and educational videos.


Please Support the Horticultural Therapy Institute on Colorado Gives Day!
Colorado’s largest day of giving, Colorado Gives Day, is Tuesday, December 5, 2017. On this day, thousands of people come together to support Colorado nonprofits like ours. When you donate to HTI, you’re helping us train horticultural therapists to work with aging adults, at-risk youth, veterans, and those recovering from illness, addiction or imprisonment. Through videos and other communications, you’re also helping us educate community groups about the power and value of horticultural therapy to heal and rehabilitate those in need.
Please help us reach our goal of $3,000. You can give as little as $10. Every donation counts. When we receive your tax-deductible donation on Dec. 5, we will receive a portion of a special $1 million incentive fund. Also, beginning November 1, you can schedule your donation early! In addition to secure online donations we accept personal checks. Checks can be mailed to: Horticultural Therapy Institute, P.O. Box 461189, Denver, CO 80246.
