Advisory Board

Dr Marina Malthouse MBBS, DipPalMed, MA(Med Hum), EdD

Current roles: Retired Palliative Care Consultant, Charity work

From 1982, working in diverse medical environments (anaesthetics, heart transplantation and General Practice) led me into my passionate vortex for palliative care. From 1995 to 2015, working in an area of medicine that only deals with death and dying meant expanding my medical toolkit by studying how to develop my care for patients and their families in additional ways. I also researched how medical education addresses end of life care. Through narrative, I researched how doctors might ‘know’ death in ways other than as a medical failure and that when personal and professional experiences consciously merge, a more compassionate care emerges from within. Education to healthcare practitioners was fundamental to my work that included the arts for its qualities of slowing down perception and expanding our conception of the ways in which we know. Also, writing and using stories to learn from, rather than be traumatised by significant experiences in medical lives. After 33 years, I retired from medicine in 2015 in order to pursue additional identities and interests. This has included volunteering for refugees in Greece and in a holistic education centre in Greece, learning about permaculture, qualifying as a TEFL teacher, and marking MSc’s and Doctorates for Cardiff and Middlesex Universities.

Dr David Zigmond MB ChB MRCGP DPM

Current roles: Physician in Psychological Medicine, Retired GP

My initial medical training was in the 1960s. My subsequent decades of work have been as a frontline practitioner: as a small practice GP and a large hospital psychiatrist and psychotherapist. From the beginning of my work I have been intrigued by how we may best understand, balance and weave together art and science; humanism and technology; imagination and data. I believe that much of our current malaise in healthcare services is due to losing sight of these questions, and then our better sense and sensibility.
