"I ATTRIBUTE MUCH OF MY SUCCESS AS A TRIAL LAWYER TO GROWING UP AND WORKING IN THE LEHIGH VALLEY, WHERE I LEARNED THE VALUES OF HARD WORK, HONOR, AND RESPECT FOR OTHERS."

Mark served on the Board of Governors of the Pennsylvania Association for Justice for almost a decade. He was one of only 10 attorneys in the State asked to serve as a founding member and director of the Pennsylvania Association for Justice Auto Negligence Section. Mark is a member of the Donald E. Wieand Barristers’ Inn, an organization dedicated to professionalism in law and comprised of a select group of attorneys and judges. He was elected Secretary/Treasurer of the Inn in 2007 and Counselor to the Inn in 2011. He was elected President of the Inn in 2013 and served a two-year term.

Mark was born and raised in Pen Argyl, Pennsylvania, a small town located in the northern Lehigh Valley. He helped pay his way through college and law school by doing construction and manufacturing work, including working one summer in a local slate quarry making roofing slate and slate chalkboards. Mark still enjoys construction work as a hobby, completing projects such as an addition to his home.

When he graduated from law school, Mark knew he wanted to return to the Lehigh Valley to give back to the community where he was raised, to fight for the rights of the good, hard-working people of this community, and to raise his family with the same values he was taught. Mark and his wife, Jennifer, live in Lower Saucon Township with their three wonderful daughters, Rachel, Meghan and Abigail.
