Mary is passionate about sharing her business and construction knowledge with young women.  She is honored to be involved in the NAWIC Philadelphia Foundation MyWIC camp each year that provides a free educational experience for girls to learn about the local trades and businesses.   “MyWIC offers a meaningful learning experience to young women that at the very least provides food for thought as they contemplate their future in the workforce”, states Mary. 

Mary also enjoys working on the committee for a block building competition called Block Kids.  The competition is for students in 1st through 6th Grade.  Block Kids is a national program where the winner of the local competition advances on to the Eastern Regional competition, with a potential to be entered into the National competition.

Mary resides in Edgmont, PA with her husband of 42 years.  Besides being in business together, they share one of their proudest achievements in raising four successful, college-degreed children.  Mary is an avid Flyers fan and intends to visit every national hockey arena to see her team play.
