I have been a consultant in Blackpool since January 2014, having previously worked as a consultant in Bolton for over 10 years. The move to Blackpool was prompted by the need for a change and the interest of working in a tertiary centre allowing more specialised work including involvement with autologous stem cell transplantation and registrar training as well as the fact that Lancashire and the Fylde coast is a very attractive place and I grew up in this part of the UK. The service has excellent research centre which has allowed me to get involved with national and commercial trials not possible during my time in Bolton. The more recent collaborative work with Lancashire Teaching hospitals to create a new Lancashire Haematology Centre has been the next step in our continually improving and expanding the service as a whole and we have recruited many additional staff during this time which has been very interesting to be part of. My main subspecialist interest is myeloma, amyloidosis and other lymphoproliferative disorders in general but I also enjoy general haematology and blood film and bone marrow morphology.
