Shawn M. Collins Super Lawyers 10 Yearse BadgeShawn Collins - Best Lawyers 2021 Leading Lawyeres 2023 Leading Lawyeres 2023 Stand Out Lawyer 2024

An outstanding trial attorney, Shawn Collins is at his best in a courtroom. Since 1986, Shawn Collins has combined his powerful communication skills with an unrelenting commitment to his clients' causes to win trials and secure favorable settlements in courts across America. Shawn has extensive experience handling "high stakes" litigation in the following areas:

  • Environmental contamination
  • Toxic chemical contamination
  • Personal injury
  • Wrongful death
  • Product liability
  • Business fraud
  • Partnership/ownership disputes
  • Breach of contract
  • Unfair business practices
  • Injunctions

His success can be measured in the results he has earned for his clients. Most recently, Shawn served as co-counsel in a case resulting in a $363 million jury verdict for a woman who contracted breast cancer after decades of exposure to the defendant's ethylene oxide. He has also been instrumental in acquiring clean water and contamination-free homes for thousands of families. In addition, Shawn has recovered millions on behalf of clients, including: $34.5 million for a neighborhood with toxic vapor intrusion, $10 million on behalf of homeowners whose wells were contaminated by dangerous chemicals; $8.5 million for the wrongful death of a firefighter killed in a motor vehicle accident; $16.9 million for families in a groundwater contamination case; $8.19 million for a town with vapor and groundwater contamination; more than $12 million for plaintiffs who contracted cancer after exposure to toxic chemicals; $8 million in settlements to families affected by landfill contamination, and over $30 million for condominium owners in property disputes.

Shawn M. Collins - Sterigenics

Shawn has been named as one of the Top 100 Trial Lawyers by The American Trial Lawyers Association from 2005 through 2022, a designation extended only to those attorneys "who exemplify superior qualifications of leadership, reputation, influence, stature, and profile as civil plaintiff or criminal defense trial lawyers." Shawn is also a "Leading Lawyer", a distinction earned by fewer than 5% of all lawyers in Illinois, and one that is decided upon by peers in the legal community. In addition, since 2005, Shawn has repeatedly been selected as an Illinois "Super Lawyer", most recently in 2023. Shawn has also been recognized as a "Best Lawyer", a Top 10 Environmental Trial Lawyer, and AV Preeminent by Martindale Hubbell. He has been selected for the Irish Legal 100, a list of the most distinguished legal professionals in the U.S. with Irish roots, and received a Lifetime Achievement Award from America's Top 100 Attorneys, an award reserved for only 100 attorneys in each state. Less than one-half of one percent of active attorneys in the United States will receive this honor. Shawn is also member of the National Association of Distinguished Counsel and a Fellow in the Litigation Counsel of America, a trial lawyer  honorary society. Fellowship in the LCA is by invitation only, and fellows are selected based on excellence and accomplishment in litigation.

Since starting The Collins Law Firm's environmental practice over 20 years ago, Shawn has dedicated the great majority of his professional life to making state and federal laws deliver justice for his individual and community-based class clients whose air, soil or water has been contaminated with carcinogens. Leading a team of committed environmental advocates, Shawn has secured for his environmental case clients hundreds of millions of dollars in environmental investigation, testing and remedy, including the cleanup of aquifers badly-contaminated with carcinogens; clean water for families and municipalities whose water supplies were threatened; and the installation of extensive in-home systems to protect residents against the intrusion into their homes of highly toxic chemical vapors. Shawn and CLF have also secured more than $100 million in financial compensation for their clients, in addition to guarantees of homes values in communities where home values were threatened by pollution.

These results were achieved over more than two decades in some 20 large environmental cases throughout the Midwest, where Shawn and CLF sought to hold corporate polluters accountable to their more than 20,000 clients. Each case was either a class action, or a consolidation of many individual cases. Each posed daunting challenges—procedurally (in achieving the consolidation of many individual cases, or getting classes certified over vigorous opposition); legally (in seeking novel applications of the law); scientifically (as the cases required mastery of complex issues in hydrogeology, toxicology and various engineering sciences); and financially (as CLF was often up against some of the largest corporations and law firms in the country, determined to exhaust CLF resources). Shawn aggressively invoked both state and federal law—pressing common law claims for negligence, trespass and negligence; claims under state environmental statutes; and claims under federal statutes, such as RCRA and CERCLA. 

Shawn has typically served as the lead or co-lead counsel for his clients in all aspects of these cases, leading lawyer teams in the formation of overall case strategy and all other important aspects of the cases, and serving usually as the lead advocate in briefing and argument before courts, and in evidentiary presentations and at trials. In 2019, Shawn and CLF were appointed as co-lead counsel (along with MBG) in the largest consolidated toxic tort mass action in Illinois history, In re Willowbrook Ethylene Oxide Litigation, pending in Cook County state court in Chicago. There, Shawn and CLF advocate for more than 750 residents of Western Suburban Chicago, who allege that their breast and blood cancers were caused by exposure to defendants’ emission for decades of a known human carcinogen, ethylene oxide.

Since founding The Collins Law Firm in 1992, Shawn has been a frequent lecturer to bar associations, civic organizations and business groups on legal and environmental topics, as well as a key speaker in many webinars and conferences. Shawn is also routinely asked by the media to share his experience on various matters. In addition to his cases being covered on ABC, CBS, NBC, and Fox, Shawn has spoken with CNN's Dr. Sanjay Gupta on a CNN special report concerning "Toxic Schools." and with Dr. Drew Pinsky about a disturbing illness at a high school in New York and the environmental investigation to find a cause. More recently, he has been a guest panelist on Court TV.

Shawn also co-authored a book, "Environmental Legal Insights; Top Environmental Lawyers Share What They Know Best". Shawn's chapter is entitled This Land is Our Land: Why We Must Count on Ourselves to Protect against Pollution. It deals with his experiences in investigating and litigating environmental contamination cases, and their impact on the environment and the people who live there.

After graduating Summa Cum Laude from the University of Notre Dame in 1980 with a B.B.A. in accounting, Shawn worked as an auditor for the Chicago office of Peat, Marwick & Mitchell (now KPMG) before deciding to pursue a law career. Shawn received his law degree from The University of Chicago Law School in 1986. He is also a Certified Public Accountant in the State of Illinois.

Shawn is a member of the American Association for Justice, the Illinois Trial Lawyers, the National Trial Lawyers, and the Illinois and Chicago Bar Associations. Shawn has also been honored as a finalist for the Daily Herald newspaper's "person of the year" award for his work on behalf of the families in Lisle, Illinois to secure a safe source of drinking water after learning their groundwater had been contaminated with TCE.

Client Reviews
Shawn Collins is a very talented lawyer, as are all the attorneys on his team. I've known and worked with Shawn for more that 30 years. Not only is he a top notch technical litigator but his communication skills are second to none. If anyone I know is ever in need of an attorney, Shawn is my very first recommendation. He gives very solid advice that goes beyond the law. He is someone you can trust to tell you the truth so you are not lead astray in the complex legal world. You really can't find a better advocate. E.M.
We were incredibly satisfied with our experience with The Collins Law Firm. We worked closely with Ed Manzke and found that he had a personal touch and truly got to know us in addition to being knowledgeable and effective in his field. The caring and individual attitude helped us tremendously throughout the entire process and we always felt like our case was in safe hands. We would highly recommend The Collins Law Firm for both its stellar work and dedicated employees. M.A.
My father recommended The Collins Law Firm to me after watching Shawn Collins and Ed Manzke at trial representing Lisle residents against Lockformer. For years, he told us courtroom tales about Shawn and Ed, citing their incredible skill as trial lawyers and how they put the huge Lockformer legal team to shame. So when my son was the victim of a wrongful death, they were my first and only choice. I can't say enough to truly express how grateful I am to The Collin's Law Firm for all that they did for me and my family. This amazing team advocated for me in my darkest moments, surpassing my expectations in every way. I will be forever grateful to Shawn and Ed. K.D.
I have worked with Rob, Shawn and The Collins Law Firm team in connection with both complex business transactions and litigation over the past several years. Shawn is far and away the best business litigation attorney I have worked with. Rob has been our lead attorney on M&A and corporate restructures, and he has delivered each time, and on time. I would highly recommend Rob to get the deal done! W.D.
Rob has been our out-side General Counsel for ten years. As a business with a global presence, it is important that we have the very best legal representation. Rob and the team have guided us through litigation battles, negotiating and drafting our important business contracts, and advising us in our business strategies. He has a great team of lawyers working with him. M.F.
