About me

I was raised in Chester County since the age of 5 and I've continued to live and work in one of the best counties in the country.


I've been married to a wonderful woman, my best friend, for 32 years this year (2014) and together we have raised five beautiful, successful young women; one who is currently in law school and one who plays women's lacrosse for Temple University.


I've had the privilege of practicing with the same firm since March of 1989, having become a partner in the firm in 1996.


I've tried to be the best advocate I could be for all of my clients and I believe I've gained the respect and admiration of my peers in the legal community throughout my over 25 years practicing law.


I and my firm would be more than happy to try and assist you in whatever legal matter you may have.


Please contact me.
