Marty is a member of the firm’s Real Estate and Environment & Energy practice groups. Prior to moving to private practice, he has spent more than two decades as a litigator at the Pennsylvania Department of Environmental Protection. In his time at the DEP, he handled more than 250 appeals in state and federal courts and in front of the Pennsylvania Environmental Hearing Board. Marty handled numerous matters involving solid waste, clean water, HSCA/CERCLA, environmental remediation, storage tanks, and sewage planning. His cases resulted in tens of millions of dollars of environmental remediation and civil penalties throughout Pennsylvania.

In the private sector, Marty has worked with businesses on both environmental and energy issues. He’s helped companies in real estate transactions navigate environmental issues, worked with municipalities on stormwater and sewage issues and has assisted companies and other entities in addressing DEP and U.S. Environmental Protection Agency enforcement actions and in obtaining permits. He’s also worked with out-of-state gas pipeline owners and contractors to help them comply with Pennsylvania environmental requirements and defended them in DEP enforcement actions. Marty is also a trained mediator.

In addition to his time at the DEP, Marty has worked in federal government positions at the U.S. Centers for Disease Control and Prevention, the Agency for Toxic Substances and Disease Registry in Atlanta, and with the Department of Energy’s Pacific Northwest Laboratory in Washington state.

Marty is a prolific speaker at professional gatherings throughout Pennsylvania on environmental topics, including Pennsylvania’s Environmental Rights Amendment, Pennsylvania’s voluntary cleanup program, PFAS contamination issues, Chesapeake Bay and clean water issues, and municipal stormwater requirements. He also co-authored the chapter on Pennsylvania’s Land Recycling and Environmental Remediation Standards Act (Act 2) in the Pennsylvania Environmental Law & Practice, 10th Edition.

His professional environmental experience has led him to leadership positions with a multitude of nonprofit organizations both in central Pennsylvania and throughout the Mid-Atlantic. He’s also a former member of the Board of School Directors for the Lower Dauphin School District.
