magna cum laude
When I look at an environmental case, I focus on the people affected and how science supports our claim. It can be a tiny detail, finding a specific toxic chemical or data that can turn a case in our client’s favor. It’s my job to find the “needle in the haystack.”

Mark Cuker is one of the foremost environmental litigation attorneys in the country. Some of his high-profile toxic tort cases – most notably the Toms River case along with colleague Esther Berezofsky– have been profiled in books, television news programs and on the internet.
Toms River involved children who were developing cancer at an alarming rate — so high that the New Jersey town was designated a “cancer cluster.” The community demanded answers, and, shepherded by the Williams Cuker Berezofsky team, they discovered that the town’s drinking water had been polluted by chemicals like styrene-acrylonitrile (SAN) trimer and by-products of dye manufacturing for decades.
“Environmental toxic dangers are routinely downplayed by the authorities or the perpetrating source–so communities need to be concerned–even skeptical– about what they‘re told. And they need an advocate.“
His practice also concentrates on consumer advocacy, including challenging unfair business practices.
Mr. Cuker has successfully represented consumers in three cases before the New Jersey Supreme Court:
Select cases, past and present:
“My parents owned a small “mom & pop“ business; a convenience store. They had been victims of persecution, and I grew up with the strong sense of what happens when injustice is unrestrained. I wanted to make things better in some form or fashion, and that‘s why I went into law.“
Mr. Cuker is a member of the National Association of Consumer Advocates, the Philadelphia Trial Lawyers Associations and Trial Lawyers for Public Justice.
He is also a member of the Board of Directors of TEACH (Toxic Environments Affect Children’s Health).
Both Mr. Cuker and the firm of Williams, Cuker & Berezofsky have been rated “AV Preeminent,” the highest rating given by legal publisher Martindale-Hubbell.
In 2006-2010 and 2013-2016 he was named a Pennsylvania Super Lawyer for class action/mass torts and environmental litigation.
Mr. Cuker is sought after by news media for commentary and analysis. He is a frequent speaker for the legal community, civic groups and others who seek up-to-the minute information on legal issues affecting consumers, businesses, municipalities and the environment. His news appearances are listed on the news and blog pages of this website.
Featured speaker: “Generic and Brand Name Drug Liability” at the Eighth Annual Judicial Symposium on Civil Justice Issues, November 2013, George Mason University School of Law.
