I am a Consultant General Surgeon with a special interest in breast, endocrine and melanoma surgery. I have practiced at St. Vincent¿s University Hospital and with the Merrion Unit of Breast Check, the National Breast Screening program, since April 2005 and also at St. Vincent's Private Hospital.I am an honorary Senior Lecturer with University College Dublin and I have a teaching and training commitment to undergraduate and post graduate trainees to fellowship level.I am an ATLS course director and have a significant surgical training commitment.

I am a past president of The Irish Hospital Consultants Association and am currently Chairman of St. Vincent's University Hospital Medical Board.

I am attached to the Breast Endocrine service in St. Vincent¿s University Hospital, Ireland East.  The unit has a focus on breast cancer and is primarily focused on the diagnosis and treatment of more than 500 new cases of breast cancer a year in conjunction with the Breastcheck program.  Multidisciplinary care is completely intergrated within the group.

There is also a specialist focus on endocrine and melanoma surgery and a strong clinical research component.
