James is an interventional and clinical cardiologist with over 10 years’ experience in complex coronary intervention (stenting). After starting at St George Hospital as an intern in 2000, there was a continuous association with the hospital through physician training, specialist training and then a PhD at UNSW. 

Final training in interventional cardiology was completed in Ottawa, Canada, prior to returning to St George Hospital as a staff specialist in 2010. Current appointments are as a staff specialist in interventional cardiology at Royal Prince Alfred hospital as well as VMO and director of the cardiac catheter laboratory at St George Private Hospital. 

Incorporated in these appointments is performance and teaching of coronary intervention that includes the full spectrum of techniques for chronic total occlusion intervention, a skill only acquired by a handful of interventional cardiologists within Australia.
