A practising general surgeon with a particular emphasis on minimally invasive techniques in the state of Georgia since 1999, my practice covers the breadth of general surgery from the common (i.e. cholecystectomies) to the rare (pheochromocytomas). Serving in leadership positions and on medical committees where I review charts on a regular basis in order to make challenging decisions on colleague's conduct and judgement has given me the skills to expeditiously review charts and make well thought out grounded recommendations.
