If you answered yes to the questions above, then you are in the right place! I look forward to connecting with you!

Leanne is an incredibly thoughtful and articulate facilitator - a delight to learn from! This program encouraged me to take a deeper look at a current HT project I am working on, and helped to ensure that I had considered all stakeholders' views, needs, and input. The models and practices suggested are very helpful for all HT/TH practitioners to learn and apply. I highly recommend this program.

Leanne Idzerda, PhD

I believe that access and connection to nature can help people to live healthier simpler lives. With a PhD in public health, I have undertaken many years of research on nature-based interventions to improve health, including social and therapeutic horticulture. I truly believe that connecting people to nature can heal the body, mind, and spirit.

After many years of listening to and working with nature-based practitioners, I heard the need for research support of their programs. I started the PurNature Design Certificate Program to help practitioners to conduct research within their therapeutic programs. The hope is that practitioners like yourselves can design and evaluate the success of your own programs and thus push the whole field forward.
