Bill Squires is Chair of the Firm’s Land Use & Development Group and a partner in the Firm’s Real Estate and Environmental Groups. Bill focuses his practice on environmental, land use, and real estate matters. He counsels corporations, developers, manufacturers, private equity firms, lenders and individuals in litigation, transactional, and regulatory settings. Bill’s practice includes the acquisition and disposition of real property and operating businesses, the cleanup of contaminated properties, compliance, enforcement defense, permitting, zoning, wetlands matters, litigation, and environmental insurance. He represents clients in state and federal courts and regularly appears before regulatory agencies and municipal boards.

Bill represents clients in disputes under state and federal law involving releases of oil and hazardous materials (including releases of PFAS and other emerging contaminants) and works closely with environmental consultants, Massachusetts licensed site professionals, engineers, risk assessors, geologists and other experts in responding to such releases. He also represents buyers, sellers and lenders in the purchase, sale and financing of operating businesses, real property, and industrial facilities. He devotes a significant portion of his practice to negotiating and structuring business transactions, drafting contracts, and negotiating environmental insurance policies. He has led environmental due diligence efforts in many national and multinational mergers and acquisitions involving complex environmental liabilities as well as permitting, compliance, and hazardous waste site cleanup issues.

Bill is also an adjunct professor at Boston University School of Law where he teaches law students how to draft and interpret contracts.
