"I've dedicated myself to getting the best results for every client. In that endeavor, I'm willing to push legal boundaries and create new law."



The former managing partner and CEO of Gilberti Stinziano Heintz & Smith, PC, Bill is a seasoned litigator who represents clients before federal and state courts and state administrative agencies, including the NYS Department of Environmental Conservation (NYSDEC), the Adirondack Park Agency, and the Public Service Commission (PSC). He regularly advocates on behalf of his clients to defend or challenge compliance with state and federal environmental laws and regulatory regimes, including solid-waste disposal, water quality, and the Navigation Law as well as local land-use determinations.

Bill additionally provides strategic legal counsel to public- and private-sector clients on large-scale project development, including the build-out of a statewide wireless communications network , a proposal to construct the world’s longest underground direct-current electric-transmission line, brownfield site development, and the construction of the region’s largest tourism destination facility.

Under Bill’s leadership at Gilberti, the firm’s environmental group cultivated one of the state’s largest mining and related transportation industry practices, representing many of the key players in the state’s construction aggregates industry. He was also the principal architect of legal arguments that helped define key principles of environmental law under both the State Environmental Quality Review Act (SEQRA) and the Mined Land Reclamation Law (MLRL).
