Our Trainers

Amos Clifford is the founder of the Association of Nature and Forest Therapy Guides and Programs and author of the best selling Your Guide to Forest Bathing (Conari Press 2018). After studying Buddhist philosophy for over 20 years, in 2004 Amos founded Sky Creek Dharma Center in Chico, California, where he emphasized the importance of meditation practice in wild places. By 2008 he no longer identified as Buddhist, instead preferring the nameless and sometimes unnamable experiences he had in natural settings, and had been having since early childhood. This led to a deepening inquiry regarding relationships between humans and the more-than-human world. Between 2010 and 2012 Amos took his inquiry into wild places, and with the help of School of Lost Borders and Men of Spirit he had a year of intense wilderness practice, which led to the vision for the Association of Nature and Forest Therapy Guides and Programs. Inspired by the Japanese practice of Shinrin-yoku, Amos founded ANFT in 2012 and over the next two years developed what is now known as the “Standard Sequence” of the ANFT school of Forest Therapy. Amos holds a BS in Organization Development and an MA in Counseling from the University of San Francisco. He teaches about Forest Therapy and leads retreats internationally

Bansi was born in Kenya, where her early years were shaped by time spent in wild, open landscapes. Her journey later continued through the Australian outback, deepening a lifelong relationship with the wilderness as a place to recalibrate, rest, and heal.

She co-founded Wild Earth & Ocean, and has spent the past 18 years curating immersive safari experiences across Africa and beyond. Through this work, she has witnessed firsthand the profound and often transformative impact that nature can have on people.

This understanding led her to become a certified Forest Therapy Guide. She now weaves forest therapy into her offerings, supporting individuals to reconnect with nature and integrate nature-based practices into everyday life. Her work includes guided forest therapy experiences, as well as nature-based retreats and safaris.

Bansi holds a degree in Wildlife Biology from the University of Sydney and has trained as a Pilates instructor, yoga teacher, and PADI Divemaster. Her exploration of grief as an essential and often unspoken part of being human led her to study Grief Ritual Leadership with Francis Weller, author of The Wild Edge of Sorrow. That learning continues to unfold.

She feels most at home in the quiet presence of wild places; walking slowly, listening deeply, and sharing space with the seen and unseen.

My name is Vicky Kyan (aka Vix) and I grew up on the edge of the Cotswold Hills in the West of England, exploring the valleys, fields, hills and woodlands of this beautiful part of UK as a child.

My love affair with Nature started here and exploded in my early adult life when I experienced the excitement and raw power of Mother Nature while travelling through Southern Africa and witnessing close encounters with its magnificent wild life . My passion for the ocean and island life emerged on further travels through SE Asia, Australia and New Zealand in my late 20’s and I was fortunate enough to land on Aotea Great Barrier Island NZ in 1986 – which has become my home for the last 35 years.

The richness of this fully off-grid rugged volcanic landscape, with its beautiful native forests and wide open surf beaches on the edge of the Pacific, its strong and creative community, and my full and colourful life journey informs all my work as a Guide, Mentor and Trainer with ANFT.

I am a mother of 3 adult children and am proud Grandmother of 3 little boys. I have been a teacher, coach, healer and care-giver in my past life and currently run a small Nature-based Homestay retreat through my business WaiOra Wellbeing for those needing R&R and TLC. I am honoured to walk the Way of the Guide as a trainer and mentor which feels like a completion of sorts as well as an ongoing adventure each day!

I trained with Amos Clifford in Cohort 2 at Sugarloaf Ridge State Park CA in May 2015 – and have wandered the Trainers pathway since October 2016. I am passionate about this work and growing a global network of Nature and Forest Therapy Guides around the world, as well as in the Southern hemisphere.

Personally I have taken ‘Forest therapy’ out of the trees and onto the beaches, pioneering the guiding of walks on the ocean shoreline and estuaries of my island home. My tentacles are reaching far and wide as I continue to nurture and grow on my own journey while supporting others to do the same all over the world.

I am deeply connected and grateful to both my Motherland and my chosen Homeland, and I’m passionate about helping people reconnect with themslelves, each other and the more than Human world through this work.

My bliss is in witnessing others stepping into their gifts and shining more fully, and I believe this is the way forward through these challenging times of global transformation on so many levels. I also ackowledge my teachers from the Human and More than Human world and all those whose shoulders I have stood upon and who have opened their hearts and minds with courage and joy.
