About my research
I am a specialist venous surgeon who performed the first endovenous surgery for varicose veins in the UK in March 1999, the first TRLOP in the world in 2000, the first microwave closure of varicose veins one in the UK in 2019 and the first non-invasive HIFU closure of varicose veins in the UK in 2019.
