Specialises in

I am a Consultant Urological Surgeon and Andrologist. I routinely perform the gold standard holmium laser enucleation of the prostate (HoLEP) surgery for men with severe urinary symptoms as well the newer techniques of Rezum and UroLift®. I am also a specialist in the management of men with both erectile and male fertility problems using the latest techniques including micro-surgery.

I qualified from UCL Medical School in London in 1997 and then trained in the major teaching hospitals in London including UCLH, The Royal Free and Imperial College. I undertook an MD research thesis on smooth muscle physiology at The Wolfson Institute at UCL and am a leading expert in male health.

I am a Consultant at Frimley Health, an Hon Consultant at Imperial College and a national mentor for HoLEP and andrology.

I regularly teach on national and international courses and have a passion for treating patients using minimally invasive techniques so that they may return to normal activities quickly.

I have published and presented extensively in the field of andrology, and previously won the prestigious International Society for Sexual Medicine Young Investigator Award.

I have been extremely fortunate to be able to balance a busy medical career with a wonderful family life including four children that keep us on our toes! I could only do this with the support of my extremely supportive wife Harvey. In my spare time, I am a keen sportsman with a particular interest in tennis and cricket.
