Urological Oncology


General Medical Council: 4713476




I am a Consultant Urological Surgeon based in Surrey and London. I grew up near Southampton, where I attended school and then graduated from the University of Nottingham Medical School. My basic surgical training was in London and Bristol, followed by an 18 month period of research at University College Hospital London (with a thesis on the diagnostic role of multiparametric MRI in prostate cancer) resulting in an MD(Res) higher degree. 

My subsequent higher SpR urological surgery training in London (Imperial North West London rotation - St Mary's Hospital, Royal Marsden Hospital, West Middlesex Hospital, Hillingdon Hospital, Watford General Hospital, Charing Cross Hospital and Northwick Park Hospital) included a year sub-specialty training in surgical treatments for kidney and ureteric stone disease at Charing Cross Hospital, London.

I have held a substantive NHS Consultant post at Ashford and St Peter's Hospitals NHS Trust since April 2015. I am the Foundation Year 2 Training Programme Director and am also the Lead Cancer Clinician for Ashford and St Peter's Hospitals NHS Trust.

I aim to provide an approachable, open and collaborative approach towards the health and care of my patients with a drive towards adopting modern treatments and knowledge, with the aim to achieving the best outcome for my patients.
