"Patients feel supported throughout their journey with safety and quality being the primary focus at Spire Clare Park. These qualities reflect my ethos as a clinician and surgeon and why I have chosen to work here."

Specialises in

I have been a Consultant Plastic Surgeon at the Royal Marsden Hospital since 2017. I specialise in complex reconstructions and in the aesthetics of the breast and trunk.

I specialise on all aspect of breast surgery, including cosmetic, reconstructive and liposculpture. I also specialise on surgery of the trunk, such as tummy tucks and liposuction. Other areas of interest include the eyelids and surgery of the skin, including moles and skin cancers.

I perform in excess of 200 breast, trunk and skin operations per year.

I have completed a management MPhil from the University of Cambridge. In 2018 I was in charge of orgnising the first London complex skin cancer educational meeting, held at the Royal Marsden Hospital in Chelsea. I graduated with distinctions from University College London Medical School in 2003 and completed my higher plastic surgery training in London, with specialist fellowships at the Royal Marsden and Queen Victoria Hospitals.

I am currently leading the microsurgical fellowship programme at the Royal Marsden Hospital. We are improving the way of training young surgeons with more exposure to operations and access to a microsurgery laboratory for practice. I am also active in research and I lead a small research team of junior doctors.

I have recently been nominated for the prestigious LaingBuisson award for my work on drainless surgery and for the reduction in patient hospital stay at the Royal Marsden Hospital. My research team, led by myself, has also recently won two prestigious awards for our research on clinical outcomes in breast reconstruction. I have a special interest in surgical innovation and I was awarded The Life Sciences Entrepreneur of the Year Award, from Cambridge University in 2013.
