In 2012 he founded Phoenix Health (a cross-specialty group with an enviable reputation as one of the UKs leading providers of NHS and private obesity surgery). In addition to his hands-on managerial role leading the Phoenix team, he performs a wide range of laparoscopic bariatric procedures including a high caseload of very complex revisional work. He remains committed to surgical training and research through a Fellowship programme funded by Phoenix Health.
