I really enjoyed working with the Thiel cadavers compared to fresh frozen specimens.

Hear from the professionals who have attended one of John's Dissection courses.
Each day blends thought-provoking presentations with hands-on dissection of fresh human cadaver specimens, guided by an international team of fascia pioneers. Rather than labelling structures, participants engage with tissue contemplatively — through a somatic and ontological lens rooted in connection, responsiveness, and becoming.
Both scientific and experiential, this retreat is designed for healthcare professionals, movement specialists, neuromuscular and manual therapists, and anyone seeking a deeper understanding of the human form through a fascial lens.
By the end of this retreat, participants will be able to:
The three-day retreat combines morning presentations with extensive hands-on dissection of fresh human cadavers, guided by Clinical Anatomist John Sharkey and his team throughout. Day One begins with registration at 8:30am; Days Two and Three run 9:00am–5:00pm.
Day One — Foundational principles of fascia as a dynamic, living process. Dissection lab exploring the fascia system and its interconnections.
Day Two — Embryological origins and fascial specialisation. Dissection lab focused on fascial and osseofascial structures.
Day Three — BioTensegrity architecture and fascia's role in movement and motion. Dissection lab with group discussion on self-assembly and loading history.
There is no formal assessment. Participants are encouraged to engage in personal enquiry and open discussion throughout. Course content, presenters and schedule may be subject to change.

In 2016, Mark began participating in biotensegrity focused dissections with John Sharkey, a world-renowned anatomist. This experience has led Mark to shift his understanding of human anatomy into the 21st century and has allowed him to apply biotensegrity principles to his work as a Strength and Conditioning trainer and Pilates teacher.
Mark’s expertise and experience have made him a highly respected and sought-after practitioner in his field. His dedication to advancing the field of fitness and wellness and his commitment to incorporating the latest research and techniques into his work have helped many clients achieve their goals and improve their overall health and well-being.

Karen Kirkness obtained her PhD in Medical Sciences at Hull York Medical School. She also holds two master’s degrees – one in Fine Art and the other in Human Anatomy from the University of Edinburgh Biomedical Sciences. Karen is the author of Spiral Bound: Integrated Anatomy for Yoga, which is a multidisciplinary book that explores the anatomical basis of spirality in human movement.
Karen is a Senior Yoga Teacher, E-RYT 500, and YACEP, accredited with the Yoga Alliance Professionals. She founded Meadowlark Yoga, a social enterprise studio, in 2008. Karen has embraced an inter-lineage approach to yoga that is focused on healing, facilitating a constraints-led journey towards self-care and personal growth for all levels of practitioners.

As a member of the BioTensegrity Interest Group (B.I.G.), Joanne is deeply interested in the application of BioTensegrity principles to the understanding of the human blueprint and natural biomotional organisation. She is dedicated to making this emerging context for human movement more accessible and understandable through her writing and workshops.
Joanne is also a CMED Graduate (2004) and has extensively studied human development, with a particular focus on soft tissue and the connections between archetypal behavior and physiology. Her rigorous studies include Human Dissection and movement research in Fascial Fitness with Robert Schleip.

John Sharkey is a well-known international educator, author, and expert in various fields such as Clinical Anatomy, Exercise Physiology, human movement, and manual treatment of chronic pain using European Neuromuscular Therapy.
