Annet Gamell NEDAnnet Gammel
Non-Executive Director

Following her training, Annet chose general practice. Prior to settling in an area and into a partnership she wanted to work abroad and was offered an opportunity to work in the Sudan at the time of Ethiopian famine. She found this to be an “amazing experience” – tough, challenging and personally rewarding – dealing with real life and death situations where the key factors were sanitation, clean water and immunisation.

Returning to general practice in Buckinghamshire, she was determined that the learning she has taken from her Sudan experience would influence her and consequently she has developed a keen interest in “whole systems” and the inter relationships between public health, housing, social services and the NHS, as well as population health.

Annet enjoys being challenged and so took on roles such as finding land and developing new practice premises, and then when clinical commissioning was introduced, she became active in persuading colleagues to form collaboratives with neighbouring areas, initially being a Board member and then in 2013, she was appointed as CEO/ Chief Clinical Officer of NHS Chiltern CCG.

In 2015 she became Chair of the Thames Valley Urgent and Emergency Care network. Annet resigned as CEO in 2016 and has since become a Board Member and Chair of the Primary Care Committee of NHS Ealing CCG.
