About

Bio

As I have made 50 I am renewed in my passion for medicine. My priorities have now changed as I am an "empty nester." I hope to pursue other areas of medicine such as the social media provided by Health Tap, The Academy of Neurology, and my local community. I am an avid Philadelphia sports fan and enjoy playing fantasy baseball and football. I try to work out regularly but love to find an excuse otherwise. I look forward to more travel with my wife and an opportunity to pursue other hobbies and keep my brain stimulated!

Specialties
