At 17 years old, it's difficult to decide where you want your career to take you.  I chose medicine because there was a long history of doctors in family, and have never regretted this choice.  I obtained a fantastic training in basic and clinical medicine at UCD which has stood me well throughout my career.  After leaving medical school I spent 6 years as a house officer and registrar in medicine and ultimately in medical oncology. 

I moved to the US in 1994 to continue my training and take part in research in oncology.  The training I received in Ireland was a wonderful basis for everything I have achieved subsequently.  I did residency and fellowship at Northwestern University and was on faculty there for 3 years before moving to Atlanta.  I developed an interest in breast cancer during my fellowship and have focused in this area since that time"

A native of Dublin, Ireland, Dr. O’Regan earned her medical degree at University College in Dublin.
