Meet Your Instructors

Emilee Weaver

Emilee (she/her) credits the lush, fern and moss-filled forests of New Hampshire, and her grandmother’s influence, for nurturing her love of nature and her ability to form meaningful connections with plants. This lifelong passion has guided her through more than 25 years in professional horticulture, a degree in social work, and a horticultural therapy certificate from the Horticultural Therapy Institute.

Her deep passion for accompanying people on their healing and learning journeys led Emilee to spend the past 15+ years building TH and HT programs and educational programs that span diverse clinical and community settings and students. She was the lead content creator and instructor for the online and hybrid TH certificate programs co-created by two prominent universities and is proud to have co-authored one of the first comprehensive HT textbooks in the field, The Profession and Practice of Horticultural Therapy, published in 2019.  

Emilee has worked with a wide range of populations and has centered her work primarily around the intersections of TH/HT and mental health. She has developed therapeutic and vocational programs in a range of inpatient psychiatric settings, botanical gardens, farms, elder care communities, and most recently pioneered a partnership with Ukrainian and Armenian botanical gardens and clinicians seeking TH training to assist citizens experiencing the trauma of war.

In her free time, you’ll find her tending and chatting with her gardens, chasing after her tortoises, preventing her cats from taking over the world, and spending time with friends and family whose support has inspired and guided her journey.

Katie McGillivray, HTR

Katie (she/her) is a Registered Horticultural Therapist (HTR) and a member of the Canadian Horticultural Therapy Association. A strong advocate of asset-based community development and reflective practice, Katie has been supporting therapeutic horticulture projects and programs for a wide variety of populations since 2014.

Katie completed her horticultural therapy certificate with Ann Kent and was proud to “build her own degree” in therapeutic horticulture, completing a minor in counselling and majoring in general studies, focusing on courses in horticulture, agriculture, psychology and research. Katie is passionate about increasing access to therapeutic horticulture in communities and facilitates regular in-person and virtual sessions. Her approach is collaborative, client-centred and strengths-based.

Katie is also a major foodie and her work in therapeutic horticulture often intersects with community food security and food justice work. When not in the garden, Katie loves cooking, entertaining and paddle boarding.
