As a physician specialized in herbal medicine, published author, trained in equine therapeutic mediation, I teach a mindful approach of horse.s My professional experience includes scientific approaches to herbal medicine, as a consultant for Pierre Fabre, and pharmacology, with a decade of experience as a specialist in adverse drug reactions, in France and Canada, for Sandoz Pharm. and IPPM Santé, among others.

I have studied the traditional medical systems of the indigenous peoples of North America, was graduated in an  anthropology D.U. from the ULP Strasbourg and the Hôpital Ste Anne (Paris), and have experienced some of these practices during numerous stays in the Diné (Navajo) and Apache nations, in the Southwestern United States.  


Since 2010, with the eQuintessence team, I practice professionally equine therapeutic mediation  during individual and group sessions . I believe that only certified caregivers with specific training in therapeutic mediation and with an understanding of the sensory world and behavior of the horse should be allowed to practice therapeutic approches with horses. i've been riding for the past twenty years and was  trained in horsemanship riding. I believe that there is no "best" method to connect with horses. It is not the methods that are important, but the adaptability and curiosity. 

I also participate in therapeutic coaching sessions, with systemic group therapy practices and am trained in Internal Family System. Horses reflect and bring out all parts of our personalities, and are appropriate for working with R. Schwartz' Internal Family System (IFS) approach to psychotherapy, a powerfully transformative psychotherapy approach with scientifically proven benefits, for which I am certified. 


Trained in ethological horsemanship at the Haras de la Cense, then at the Haras de Cazeau in Belgium, I am a certified Advanced POH MH Eponaquest Instructor, after a 350 hour training course in the USA by Linda Kohanov and the Eponaquest Foundation, in connection with the University of Arizona in Tucson ( Arizona, USA).  In 2018, I was personally trained by Linda Kohanov to become an Advanced Eponaquest Instructor and as such, I am able to lead validating Eponaquest workshops. 

In partnership with the Association Cheval Communication, local associations and Equiterria Ariège, I have organized numerous cultural exchange workshops on therapeutic mediation with horses, and had the honor of inviting traditional practitioners from the Navajo, Hopi and Apache cultures, and to live with them. Our meetings  resulted in cultural exchange projects and local actions to help wild horses on Native American territories, an ethnopsychiatry thesus on the traditional uses of horses by the Navajo and Apache, in collaboration with the University Louis Pasteur in Strasbourg, and the St Anne Hospital in Paris, a leading center for ethnopsychiatry.

In 2021, I created a group for the exchange of practices and know-how: the ReSET Group for Research on Traditional Ecological Knowledge. 

In partnership with the association AMII and other humanitarian associations, I participate in actions of integration of refugees and people in exile situation where the horse is a mediator and a therapeutic actor. 

Finally, I believe that nature gives us useful models in therapy, and according to these principles of biomimicry, I have created a partnership with the Parc Naturel Forestier de Chevreuse to promote biodiversity in the Ile-de-France region by managing natural environments with horses. 

 I act in partnership with the Parc Naturel forestier de Chevreuse to promote biodiversity in the Ile-de-France region through the management of natural environments with horses. To know better the living nature which surrounds us daily, it is also to know better how to respect it.


With their innate values of community in shared governance, non-competitiveness and connection, with their power that they so kindly put at the service of humans, horses could well be one of the great assets for acquiring the know-how of tomorrow.
