Care Philosophy

My philosophy is to treat all patients as if they are family.  I understand the angst that is sometimes involved with a patient’s health and the decisions that have to be made.  I will always be happy to spend extra time to make sure everyone involved fully understand the care plan.

Personal Interests

I enjoy spending time with my wife and two children.  I also enjoy watersports, especially waterskiing, traveling and watching the Pittsburgh Steelers.
