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
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
