I am a Consultant Urological Surgeon at Ashford and St Peter’s Hospitals NHS Foundation Trust. Having grown up near Southampton and completed undergraduate training at Nottingham University Medical School, I undertook house officer posts and then senior house officer basic surgical training posts in London and Bristol.

I then undertook a period of research at University College London Hospital investigating the role of multiparametric MRI in diagnosing and excluding prostate cancer and running focal therapy trials (HIFU and photodynamic therapy), before higher urological training as an SpR on the North West London (Imperial) training scheme at St Mary’s Hospital, The Royal Marsden Hospital, West Middlesex Hospital, Charing Cross Hospital, Hillingdon Hospital and Northwick Park Hospital. I completed a year of sub-specialty training in stone surgery at Charing Cross Hospital as a senior SpR and am extremely experienced in treating kidney stones through a variety of surgical techniques (clinical stone lead at Ashford and St Peter’s Hospital NHS Trust).

I have been a consultant since April 2015 and have over 20 years of clinical experience. I treat a wide range of general urological conditions and can provide novel treatments for benign prostatic enlargement (Urolift, Rezum, Greenlight PVP, TURP surgery and prostate artery embolization). I am also able to provide prostate diagnostic services for men with raised PSA (multiparametric MRI and transperineal template mapping biopsy and targeted fusion biopsy). Evaluation for haematuria (blood in the urine) and management of bladder cancer is also part of my clinical work.

I am currently the Clinical Lead (Clinical Director) for Urology and the Lead Cancer Clinician for Ashford and St Peter’s Hospitals NHS Trust. I am the Foundation Year 2 Training Programme Director at the trust.

I am also the principal investigator at Ashford and St Peter’s Hospital for numerous prostate cancer clinical trials (PROFILE, CADMUS study, INDEX study, PRONOUNCE trial, CHRONOS and PROSPECT trials),

I strive to be available and flexible for my patients and provide a patient centred, individually tailored approach the care of my patients.
