Our legal and technical experience in both arbitration and mediation matters has made our firm a logical choice when parties are searching for an experienced and knowledgeable neutral to help resolve their environmental, land use or energy disputes. Senior Counsel Rich Williams brings extensive experience with ADR from a corporate perspective and is a certified mediator in the Delaware Superior Court. Founding partner Joe Manko and John Gullace, along with the firm's senior technical consultant Darryl Borrelli, have worked together on a number of large and complex alternative dispute resolution (ADR) matters in which MGKF had been retained to act as the neutral. 

Our team offers trusted perspective where a third-party neutral is needed, based on decades of experience in all aspects of environmental counseling and litigation. 

Rich Williams has 37 years of experience as an environmental lawyer in government, (Head of the Delaware Department of Justice’s Environmental Section), private practice and in-house practice. His experience includes environmental litigation, commercial real estate transactions, environmental aspects of M&A transactions, environmental compliance and remediation. He joined the firm after practicing in-house for more than 30 years, where his practice focused on environmental compliance and remediation, real estate, environmental aspects of business transactions and environmental litigation. Rich’s experience enables him to understand issues from all perspectives and facilitate the resolution of complex matters in innovative ways.

Darryl Borrelli has undergraduate and graduate degrees in engineering, with more than 30 years of environmental consulting experience working for MGKF, large industrial corporations, and the Department of Defense.

John Gullace has nearly three decades of experience in private practice as an environmental litigator. John has also received neutral training through Conflict Prevention Resolution (CPR).

Joe Manko has more than 50 years of experience as an environmental lawyer both in government (as Regional Counsel for U.S. Environmental Protection Agency Region III) and in private practice. He has spoken on ADR at various forums and CLE programs and was a lecturer-in-law on various environmental subjects, including ADR, at the University of Pennsylvania and Vermont Law Schools for more than two decades.
