Tammi Sweet loves to teach. It’s her superpower. She has a magical ability to connect with almost anyone when teaching and help them understand complex material.

For over 30 years, Tammi has shared her gift of teaching at various colleges, massage schools, and herbal schools throughout the country. Her background in physiology makes her an invaluable resource to developing herbalists and massage therapists who want to deepen their foundation as practitioners. 

In 2007, Tammi set out to “combine all the things I love into one curriculum and teach whatever I wanted in ways that made sense – on my own terms.” So she and her partner Kris Miller launched the Heartstone Center for Earth Essentials. 

At Heartstone, Tammi and Kris run their monthly residential Herbal Apprenticeship. She also offers online courses integrating physiology and plant medicine with Tammi’s love of teaching, such as her signature course, Anatomy & Physiology for Herbalists, advanced Physiology courses, and growing and medicine making with “The Plant.” 

Tammi’s vision is for Heartstone to co-create a space with the land where people can come “home,” take refuge and find the sacred both on the land and within themselves, and facilitate healing. When not teaching, Tammi loves to spend time alone and ‘recharge’ by exploring the land, writing, and hiking.
