The Katharine Dormandy Haemophilia Centre and Thrombosis Unit

The Katharine Dormandy Haemophilia Centre and Thrombosis Unit was founded in 1964 in Lawn Road Hospital, Hampstead, by the late Dr Katharine Dormandy. It was opened in its present form within the new Royal Free Hospital in 1978 and extended in 1994. Today the unit is one of the largest haemophilia treatment centres in Europe. Our services include:

  • comprehensive care centre for patients with inherited and acquired bleeding disorders, including diagnosis and management

  • thrombosis service for investigation and management of inherited and acquired thrombotic conditions, including a Level IV anticoagulation service

  • comprehensive laboratory services for the diagnosis and management of various inherited and acquired bleeding and thrombotic disorders, including genetic diagnosis
