 I'm John Martin. I'm a vascular surgeon with the University of Maryland Medical System. I actually see patients in the clinic in Annapolis, Maryland and have the luxury of actually operating on patients in various hospitals throughout the system based on the procedure that's necessary in the geographic location of the patients. So I see the broad spectrum of vascular problems and I'm a classically trained vascular surgeon so I have a lot of open experience. So open and closed aneurysms, carotid endarterectomy, carotid stenting, distal bypasses, peripheral angioplasty. The broad spectrum of vascular pathology I take care of. So my goal for patients is first of all to make them happy that they chose me to come see me. The second is to clearly address their health concerns and make them feel confident in the care that we're providing and at the end of the day offer them a solution that adds more life to years and years to life. You know I've been so fortunate to do so many different things in a diverse career between academics, the clinical practice of medicine, developing new technologies, clinical studies. At the end of the day for me as I get toward kind of the ladder stages it's that personal interaction and that impact you make on a family and it's really particularly interesting to me because I came back into practice after a brief hiatus developing new technology with a startup company and what I've seen most are the patients coming back to me the joy in their faces to see me back and it's been a real resounding affirmation of the practice of medicine and what difference you can make in patients' lives.
