Patients with vascular disease often face many challenges—medical and otherwise. Consequently, I recognize that there are many important aspects to your care. I also appreciate that having surgery is a major life event. With all of this in mind, I will do my best to provide you with patient-centered, high quality, effective and compassionate care.

I enjoy the challenge of the diagnostic process of medicine, which is one of the many reasons I have chosen to work as a nocturnist, which is a hospital-based physician who works overnight. In my free time, I've been known to read books about the American Revolution and Colonial Period, or attend hard rock/metal concerts. Also, '90s music is in my head all of the time.
