David is an experienced trial attorney and a member of the Firm’s litigation department. He began his career as a solo practitioner in Philadelphia practicing family law, including divorces, child/spousal support, custody and adoption matters. After moving to the Lehigh Valley, David joined up with one of the largest law firms in the valley and later realized that he could best serve his clients working in a smaller setting to ensure a better attorney/client relationship. Upon leaving that firm, David added estate planning/administration to his practice and has taken a focus on the LGBTQ rights of the Lehigh Valley citizens, serving as an active Board Member of the Greater Lehigh Valley Chamber of Commerce LGBT Business Council. David lives in Allentown with his wife and their daughter and enjoys spending time with his family, golfing, bowling and continues to play baseball on Sundays!
