About us About us CLEFT was established in 2007 by cleft surgeon Brian Sommerlad - based at Great Ormond Street Hospital for Children, together with a former patient's grandmother. CLEFT is a charity that is focused on providing permanent, sustainable ways to improve cleft care both in the UK and overseas. By supporting a variety of projects, we are helping to improve the lives of people born with clefts in many different ways. Manage Cookie Preferences
