Mr Alberic Fiennes trained at St Bart's Hospital London and qualified in 1976. After broad training in all aspects of Surgery, he became Senior Lecturer in Surgery, then Consultant Surgeon at St George's Hospital and Medical School from 1990 to 2007, where he founded the current bariatric service. He was Director of Bariatric Surgery at University College London Hospital from 2007-2009. He is currently Secretary and President Elect of the British Obesity and Metabolic Surgery Society (BOMSS).

An early convert to laparoscopic surgery, Mr Fiennes undertook keyhole gallbladder surgery from 1991 and contributed internationally to the development of keyhole 'TEPP' hernia repair from 1992. He was the first UK surgeon to offer these operations as day surgery. He has been active in Bariatric Surgery, both keyhole and open, since 1995 when he took on the aftercare of patients who had undergone weight-loss surgery in the 1970s and 80s, working over the years with leading colleagues in this field. The team he now leads has fourteen years experience, during which time he has undertaken nearly a thousand procedures and has trained many fellow bariatric surgeons. The same experience has taught him not only to be a committed patient advocate, but to empathise with the needs, fears and hopes of patients seeking bariatric surgery.

Mr Fiennes is now privileged to lead a team of professionals with long NHS and independent sector experience who share one passion: to support patients in their recovery from the 21st century disease of severe overweight.
