Dr Siân Roberts


MB BS (St Bartholomew’s, London 1992) MRCGP DRCOG DCH

I qualified at St Bartholomew's College (London) in 1992 and since then I have worked as a Medical Officer in the RAF, lived in China, worked in private practice in Singapore, before returning to work in the NHS in 2003.

Although I consider myself a 'general' GP, I do have particular interests in women's health, child health and psychological health but I am happy to treat all that crosses the threshold!

I am passionate about people, patients and health; the core reasons I became a GP. Additionally, I am using my GP experience as a Clinical Director for Chiltern CCG, to help shape health services for the local community. As a Locality Lead, I am responsible for engaging the nine practices within the Amersham and Chesham Locality with clinical commissioning.


Dr Rebecca Mallard-Smith

rjmsMB BS DFFP (Royal Free, London) 1992

I qualified as a Doctor in 1992 from the Royal Free School of Medicine in North London. After my junior doctor year I went straight into training to become a GP on the Oxford Vocational scheme and have now been qualified for 19 years and always worked locally. I currently work 6 sessions at John Hampden surgery.

I grew up and was educated locally in Buckinghamshire therefore know the area well and continue to enjoy living in the village and the its surrounding beautiful countryside.

I have been appointed by my colleagues to represent them on the Local Medical Committee (LMC) for the Chiltern and South Bucks area. I am also a qualified GP appraiser and support GPs to be revalidated locally.

More recently I have become a Commissioning Director for Chiltern CCG and am responsible for the commissioning of Urgent Care services in Buckinghamshire eg MIIU, OOH, BHT AE service, District nursing teams. As you can imagine this is a difficult role but I am happy to take the challenge and improve the quality and type of urgent care services locally that patients need.

I qualified from Nottingham Medical School in 1990 and became a fully qualified GP in 1994.

I've been living and working in Buckinghamshire since 2004 although having been born and bred in Ickenham, it felt like I was "coming home" when I moved to the area!

I have a long history with The John Hampden Surgery having done Dr Mallard-Smith's maternity locum for her 2nd child in 1998 but then there was a long gap in our acquaintance, until I started locum work for the practice again about 5 years ago. I've enjoyed regular locum sessions at the surgery over the last 5 years so when I was offered the chance of a permanent role I jumped at it!

Having been a locum for 5 years, I'm really looking forward to getting to know individual patients again and offering some continuity of care.

I live near Beaconsfield with my husband and 2 teenage sons so when I'm not working, I'm a taxi driver running my children round they have much better social lives then either of their parents!!

The practice occasionally employs locums (qualified GPs) on a temporary basis.
