Marta Sikorska

Marta SikorskaMarta Sikorska (Pasikonie, Poland)

Marta is a former member of the board in MiMer (2020-2023). 

Marta is a modality independent Equine Assisted Learning facilitator, a long time advocate for equine welfare and ethics in equine assisted activities. Marta has over 20 years of experience as teacher and educator and her work now is dedicated to developing education programmes for EAL practitioners and facilitators that are informed as far as equine ethics, welfare and also horse and human trauma.

Her path with horses started unexpectedly after her totally non-horsey family acquired an ex-racing arabian stallion. She’s been living with a small herd of horses since then, learning and growing both as a horsewoman and a human being. Having tried to understand the horse world as an adult she tried many traditional ways of interacting with horses. Her numerous disappointments and unrelenting fascination with horses pushed her to redefine concepts like leadership, freedom and partnership to get to have life with horses. She neither rides nor trains horses.

Marta is also a mediator working in Non-Violent Communication (NVC) approach. Due to her strong connection to children and dedication to her role as a parent she mostly counsels parents, couples, families and teachers. Marta offers supervision to EAL facilitators and practitioners.

She believes in combining horse and human welfare education thus creating a lens of understanding, cooperation and exchange between the two species. She’s created a NGO dedicated to promoting this very idea (www.pasikonie.pl). She loves to teach restoration and stress relief together with horses. She’s a great enthusiast of somatic approach to healing and growth.

Marta works in Polish and English.

Dru Butterfield

Dru ButterfieldDru Butterfield, trainer and consultant in equine conservation grazing, UK.

Dru is a UK based collaborator in MiMer workshops and courses.

Beautiful Dartmoor, often described as the last real wilderness of South West England, is where I developed my passion for its tough, hardy native ponies. Animals that can withstand Atlantic gales and summer droughts, it's almost as if they were built for the climatic changes we are now witnessing.

Through Equi Phoenix it is a privilege to support the many pony keepers and breeders across the UK helping promote the importance of our Native equine breeds, thus protecting our heritage as we find new uses for equines in the world of conservation to enhance biodiversity through their grazing habits.

My experience of equine conservation grazing has been gained through working with a range of native and non-native breeds, such as the Exmoor, Shetland, Welsh Mountain, Konik and the Carneddau ponies from North Wales

Much of my practical experience was gained through handling semi-feral ponies and managing a 450 hectare moorland site on Dartmoor.

During my time as Chief Executive of the Dartmoor Pony Heritage Trust, I led a research project to establish the effectiveness of equine grazing on Molinia grass using salt blocks as an attractant. The project ran for six years in partnership with Plymouth University with outstanding results.

For 16 years my equine consultancy has provided guidance, advice and training to private clients, wildlife and conservation organisations, as well as national and regional grazing NGOs across the UK.

In April 2022 I launched Equi Phoenix Ltd, we source and train equines for conservation grazing systems, equine welfare and management advice for those using or considering the use of equines in the conservation grazing sector, site and risk assessments, equine and ranger / warden / volunteer team training.

Sonja Lairila

Sonja LairilaSonja Lairila, Equine ethics and -relationship consultant & yoga instructor (Finland, Germany) 

Sonja is a long time collaborator and a former member of our Board of Directors.

Sonja has 20 years of experience in different disciplines with horses. Her passion to truly understand equines was evoked by working with many traumatized horses over the years. By being close to horses that had suffered lead her to study equines, and equine-human interaction intensively from different perspectives.

Besides horses, Sonja is a Dynamic Mindfulness yoga instructor, and her passion for movement and mindfulness reaches over to the equine world as well. She is curious about mindful movement experiences, and how that connects to the relationships/interactions with horses. She believes in the power of just being and observing in order to understand, both ourselves, and our equine partners better.

Sonja’s interdisciplinary approach aims to bring a wider understanding and better welfare to the world of equines. Her aim is to help people improve their relationships with their equine partners through mutual understanding and to improve the general welfare and wellbeing of equines (and humans) by education.

Emily Kieson

Emily Kieson

Emily Kieson PhD, M.S., PgDip, ESMHL,  (USA)

Emily is a former member of the Board in MiMer. She served as MiMer Centre's Research Director from 2019- august 2022.

Emily has a PhD in Comparative Psychology from Oklahoma State University, a MS in Psychology from Oklahoma State University, a B.S. in Ecology and Evolution from Rutgers University and a Post Graduate Diploma in Equine Science from the University of Edinburgh. She teaches and develops courses at Post University and Unity College and serves on the Equine Welfare Committee of the Professional Association of Therapeutic Horsemanship. Her passion is researching equine behavioral psychology in the context of horse-human interactions with specific focuses on affiliative strategies, social bonding, and positive welfare.

Emily has spent almost 20 years as a multi-disciplinary trainer and instructor in both Texas and Oklahoma and became interested in equine-assisted activities and therapies about ten years ago. She has been trained and certified in a half-dozen models of EAAT and continues to learn about the field. It was during these trainings that she discovered the lack of research in horse-human interactions and became interested (honestly, obsessed) with developing the science in this field. Specifically, Emily is interested in understanding how horses interact with humans in ways that mimic social bonding to help develop better models of equine-assisted psychotherapy that use equine interactions to parallel interpersonal relationships. She also has ambitions of using this to help individuals create better relationships with their horses at home and create more centralized educational resources for horse owners and equine practitioners.
