Erin C. Lentz-McMahon, Esquire

For more than a decade, Erin C. Lentz-McMahon represented clients in a wide range of family law matters. After graduating from Widener Law School in 2005, she served as a judicial law clerk to Family and Orphans’ Court of Common Pleas Judge Robert G. Bigham in Adams County, Pennsylvania. This was a unique opportunity in that Judge Bigham heard all family law matters from the earliest stages of conciliation to trial. She observed the traditional courtroom presentation of evidence by attorneys and parties to support their requests for custody, support, and relief pursuant to the Divorce Code. Erin learned firsthand that there is a limited amount of time for the Court to hear all of the evidence, and a decision will be made in a timetable set by the Courts. She also served as a judicial law clerk to the first female elected to the Pennsylvania Supreme Court Madame Justice Sandra Schultz Newman.

Erin began her practice as an Assistant District Attorney in Montgomery County, Pennsylvania in the appellate division that required attention to details with a comprehensive understanding of the applicable law. Thereafter, she opened her private law office known as the Law Offices of Erin C. Lentz, P.C. for approximately two years, at which time she represented clients in divorce, custody, support, and abuse matters. Erin joined her husband, John I. McMahon, Jr., Esquire, as a partner at the Law Offices of McMahon, McMahon & Lentz, where she continued to represent clients in litigated family law matters.

In 2012, after attending a Basic Mediation Training with Winnie Backlund, M.Ed., Erin knew that she wanted to offer an alternative to the courtroom for her clients. Private mediation became the initial alternative to litigation. She continued with two additional trainings specialized in Family, Divorce and Custody Mediation with Ms. Backlund in 2012, and Lynn E. MacBeth, J.D., ACR Approved Training Provider in 2014. In 2015, Erin completed an Advanced Mediation Skills Intensive Workshop with a Montgomery County Supervisory Mediator, Maribeth Blessing. She is in the process of becoming a court approved Mediator in Montgomery and Chester Counties for child custody matters.

Collaborative practice became the next option that Erin offers to her clients who are interested in working together to reach a solution that honors their personal interests. Each family has their own needs and concerns that Erin believes should be the focus when dealing with major life transitions to discuss cash flow, co-parenting, and separation. The Collaborative process allows her clients to make decisions together with the assistance of trained professionals. Erin is licensed to practice law in Pennsylvania and New Jersey for which she maintains continuing education primarily focused in family law. She is a member of the Montgomery County Bar Association (MBA), its Collaborative Law Committee, and the International Association of Collaborative Professionals (IACP), and the Doris Jonas Freed Inn of Court, Family Law. Erin graduated cum laude from Gannon University in 2002 with a B.A., and received a J.D. from Widener University in 2005.
