Gentle Healing of Mind and Body - Nurturing the Soul

The Institute of Biodynamic Medicine Ltd (IOBM) - formerly the Gerda Boyesen International Institute of Biodynamic Psychology and Psychotherapy Ltd (GBII) - and its clinical arm The Biodynamic Clinic, have transformed the lives of many people by helping them to restore their natural health, peace of mind and emotional well-being.

Clinical Psychologist Gerda Boyesen (1922-2005) established a new branch of knowledge known as biodynamic psychology and psychotherapy. This is a biological and psychological approach to understanding the human condition. As well as the traditional fields of psychology and psychotherapy plus physical and emotional well-being, biodynamic knowledge is increasingly being applied in the evolving fields of epigenetics, neuro-science, targeted therapies, trauma recovery, energy medicine, conflict resoluton. The biodynamic approach and perspective can bring new understanding and subsequent resolution to many biological and psychological upsets.

Gerda Boyesen's findings are confirmed by new research and discoveries in physics, medicine, cell biology, epigenetics and neuro science. Her theories throw new light on the important concept of 'life energy' and 'nervous fluid' and how this is cleared and regulated organically in the body, enabling true freedom for the mind, body, spirit and soul. 

Biodynamic Medicine

Medicine is defined as the 'art of healing'. Biodynamic Medicine is defined as the art of healing in accordance with biodynamic principles.

With the emerging evidence basis for well established biodynamic practices, IOBM is engaged in the development and application of these methods and new protocols to grow the field of Biodynamic Medicine.

Good Practice and Research

Working complementary to and along side the medical model, these methods are carefully adapted to individual needs, as well as informed by established and developing protocols.

Clinical data compiled from research studies, medical tests of our clients across a wide range of bio-markers, and anonymised case studies form a valuable ‘body’ of knowledge helpful to all interested in health and well-being.

Further clinical trials are now being developed to monitor and evaluate the effectiveness of biodynamic treatments through physiological bio-markers, tools to measure psychological well-being, and bio-physical assessments.


Many people come to biodynamic work for simple well-being and happiness, quality relaxation, pleasure and flow, to maintain vital health and strength and to enhance the joy of living. 

Our professional biodynamic services are delivered through the work of the Biodynamic Clinic and with qualified therapists on the Register of Licenced Biodynamic Practitioners.

Biodynamic Treatments - What Option is Best for You? 

Initial Consultion and Treatment - 2 Hours

This can be one-off and contract ends here if no further treatment is indicated or undertaken. 

Ongoing Sessions 

One to One individual biodynamic psychotherapy and biodynamic massage sessions are given by therapists from our Register of Licensed Biodynamic Practitioners. We recommend a minimum of 15 hours (foundation phase) and then review, plus a further 3 x 15 hour phases up to 60 hours - in order to gain the optimum benefit from your biodynamic process. 

This can be delivered as ongoing weekly or fortnightly sessions, or as 'block therapy' over a series of days (see below). Your personalised programme will be discussed and mutually agreed at the first consultation, including provision for review.

'Block Therapy' (Day or Half Day Clinic) 

As an alternative to ongoing regular sessions this specialised service involves a series of 2.5 hour (half-day clinic) or 5 hours ( 2 x 2.5 hour with lunch break) - day clinic - morning and / or afternoon sessions over 6 half days or 3 full days (foundation phase) and beyond if required.  A unique and personal programme designed around you what you need at this point in your life. Especially for those who cannot attend for ongoing regular sessions because of travel or other difficulties, or who want help with a particular issue or phase in life, or who just need a boost, or to have time and space to be in a total biodynamic environment for relaxation and restoration.

Mary Molloy



"My training helped me to feel my emotions, allow them, articulate them, and clarify my position in staying with them. I began to feel connected to the world in a new and energetic way. It helped me to get beyond my neurotic self. It facilitated my experience of energetic pulsation and rhythm."

MF. GBII Graduate and Client

"I enjoyed all of it, but especially the dialogues on Monday morning. I have waited 40 years of this life to be present and participate in this level of discussion."

MF IoBM Licensed Biodynamic Psychotherapist

"The CPD day was life enhancing. I had forgotten how 'special' these times of listening and sharing are. Safe, warm, secure, deeply moving, hilariously funny and life changing. The opportunity to learn what’s new, refresh what I already know and to hear about the developments of the work, serve to remind me of the importance of this field and body of work in the world."

BN IoBM Licensed Biodynamic Psychotherapist

"The summer school is where I first met the extraordinary and gifted Mary Molloy. Mary is a true genius in her field. Through her help I have moved into a different space in my life and dealt with things that I didn't even know that I needed to deal with. I have become a much more spiritual and self aware person because of this."

GM. Participant

"I was having difficulty in my life, communication and relationships. I have been attending biodynamic sessions for 1 -2 years and it has helped me come to terms with how my past relationships have affected my present life. It has helped the development of improved communication skills, and has helped me to understand my body to a greater degree."
