About Donald
Donald Petrille has balanced public service and private practice across more than two decades. He has moved between court-related roles and firm work, bringing procedural knowledge of probate and tax settings to routine client matters. His career shows a blend of courtroom admission and hands-on estate work.
He earned his law degree from Villanova University School of Law in 1998 after completing a bachelor’s degree in chemistry at the College of William and Mary in 1994. The science background is an uncommon preface for a lawyer whose later work would touch on tax and fiduciary administration.
Petrille’s professional path includes both firm and public positions. In 2004 he worked as a lawyer at Scott Petri & Associates, P.C. He became a shareholder at Petrille Wind, P.C. in 2007. In 2012 he took on the role of Register of Wills for the Orphans’ Court of Bucks County, Pennsylvania, a post that placed him at the center of local probate administration. That same year he joined High Swartz as Of Counsel, a role he continues to hold.
His admissions reflect a federal and regional practice. He is admitted in New Jersey and Pennsylvania. He is also admitted to the U.S. District Court for the District of New Jersey, the U.S. District Court for the Eastern District of Pennsylvania, the U.S. Court of Appeals for the Third Circuit, and the U.S. Tax Court. Those credentials support work that crosses state and federal lines and that sometimes involves tax litigation or appeals.
Petrille maintains active ties to the local bar and estate planning community. He holds memberships in the Bucks County Bar Association and the Bucks County Estate Planning Council. His service as Register of Wills and his council membership link him closely to probate procedures and the mechanics of estate administration in Bucks County.
Colleagues and court records show a practice rooted in administration and process. He has handled estate-related filings, navigated Orphans’ Court procedures, and appeared in forums where tax issues may arise. His background in tax court admissions and in local probate offices gives him familiarity with the paperwork and deadlines that determine outcomes.
He is Of Counsel at High Swartz and continues to split time between advising clients and performing court-related duties. His practice centers on estate planning, probate administration and tax-related matters.
