Stacey Frampton - Exmoor

Stacey loves plants and the sense of peace, connection and wonder felt when hanging out with them.

She likes to take advantage of all the many ways we can learn about them and what they can teach us about ourselves. She really enjoys hearing about all the ways other people connect with plants andweave them into their lives, and supporting and facilitating this process.

Stacey has experience growing food in market gardens and alongside people experiencing mental health problems. She completed the apprenticeship in 2021, has a certificate in Sustainable Food and Farming and is currently studying for an RHS certificate in Horticulture.


Karen Davis - Northern UK

As a teenager Karen chose to do a school project on Herbal medicine and scoured the library for information. Karen was fascinated by how the herbs worked in the body and wanted to learn more.  So, Karen qualified as a pharmacist as she thought this would satisfy her curiosity about how chemicals interact within the body.

As a pharmacist, Karen spent time working in a range of different cancer areas and specialised in the safe handling of anti-cancer medicines, building facilities for staff protection and education of other professionals about this. Also, she worked with cystic fibrosis patients, with mental illness and other areas. She has worked in hospitals, large companies and for a small rapidly growing start-up.

In 2021, Fiona completed the Wild Things 2 course with Grass Roots Remedies Co-op in Edinburgh and then began The Plant Medicine School’s Practitioner training course with Jane Wallwork in Exmoor. Over the past few years, Fiona has enjoyed organising events for Scottish students.

While she is completing the Herbal Practitioner course, Fiona works as an Advanced Clinical Massage Therapist in her hometown in Scotland. She is a mentor on the Plant Medicine School Scotland Apprenticeship course. She loves encouraging the enthusiasm and interest of the students on their plant medicine journey.


Tiarnan O’Sullivan -Wexford

My journey with the Plant Medicine School began in 2016 when I hopped on board at the last minute due to a cancellation in that year’s apprenticeship stream. I remember when Nikki called me to confirm my place I was working in one of the most supremely manicured gardens I have ever been in.

Everyone’s journey on the apprenticeship was unique. Some came to the class with a great deal of knowledge of holistic health, anatomy, alternative therapies and orthodox medicine, and some had even completed other herbal medicine courses and apprenticeships.


Silja Harms - Wexford

Silja started her apprenticeship at The Plant Medicine School in March 2014, completing her practitioner training in November of 2018. When The Plant Medicine School relocated to Hollyfort in 2020, she began working there. Initially supporting the creation of the herbal medicine garden and community field,

Silja found joy in assisting new apprentices on their learning journey and has extended this to include practitioner students. Her motto is “have fun” (which research has found to be the most efficient way of learning) and “keep it simple.”

“I have three things to teach: simplicity, patience, compassion. These three are your greatest treasures.” - Lao Tzu
