Marion Steiner

Family Doctor

Marion is a family doctor, working in North Bristol, since 1996.
Early on in her career, she realised that conventional medical teaching had left significant gaps in her knowledge of how to treat real patients with difficult lives, and help them improve their quality of life.

She therefore developed her therapeutic toolkit to include a broad range of approaches, and particularly to nurture patients to find their own wellbeing.
She worked as Self Care Lead for the local Clinical Commissioning Group for many years, and as an Integrative Care doctor at Penny Brohn Cancer Care, alongside her NHS practice.
