During that time I have had the opportunity to work in cancer specialist centres, hospices, community and acute hospital settings. I undertook my masters at Birkbeck in Psychodynamic Counselling and my dissertation was published in the peer-reviewed journal ‘Psychodynamic Practice’.

Martin Galligan

I have been working as a registered nurse across a variety of roles within the acute hospital setting. I have a specialist interest in pain management with the bulk of my career working within this field, with my first role as a clinical nurse specialist post managing acute and complex cancer pain at the Royal Marsden. Following this I became the lead nurse for acute and chronic pain in a busy district general hospital. In this role I was able to develop the service and improve pain education and management across the trust for both staff and patients. 

I have moved into the academic setting and I am now working as a lecturer practitioner at The Royal Marsden School and joined the team in February 2019 with a focus on advanced practice and symptom management.

Louise Trewern

Louise Trewern has lived with pain since childhood. After years of strange illnesses and infections, inconclusive tests and persistent pain, Louise was diagnosed with Fibromyalgia and Osteoarthritis. She was prescribed opioid medication for back pain, which increased over a 13 year period to dangerously high levels, along with a cocktail of other drugs such as antidepressants and benzodiazepines. With support from her local pain service Louise reduced and eventually came off her opioids and learned to self-manage her pain in other ways. She considers that this process literally ‘saved her life.’

Louise today is a very passionate patient-advocate advising The British Pain Society’s Patient Voice Committee where she is Vice Chair. She is on Executive Committee of The Physiotherapy Pain Association and Chair of the Get Involved – Evolving Through Patient Experience Committee at Torbay Hospital Pain Service, as well as numerous other projects including supporting and advising Live Well with Pain.
