He serves as Solicitor to East Brandywine Township and as Special Counsel to Straban Township for Litigation matters.

Marc offers his professional expertise and experience to work with clients who choose mediation, a form of dispute resolution, to resolve their conflicts outside of the courtroom or town meeting. This approach to resolving issues in real estate, land use and zoning disputes presents significant opportunities for dialog and control in a non-adversarial manner, allowing the parties to maintain a working relationship while lessening or eliminating the areas of conflict in a more informal, and less time-consuming and less expensive process.
