Ranked by Super Lawyers

Bill Wagner is an accomplished trial lawyer focused on complex commercial litigation (including government contracts, insurance recovery, and privacy and data security), environmental litigation, and white collar defense. His clients include manufacturers, defense contractors, and financial, professional services, and technology companies.

Bill believes trial skills and integrity matter. In an era when approximately 95% of cases settle, he has tried more than 40 cases to verdict. In the last few years, Bill defeated a 9-figure breach of contract claim against a defense contractor client; obtained preliminary and permanent injunctions to protect a client’s trade secrets from misappropriation for technology representing billions of dollars in sales; skillfully guided clients through internal investigations and high-profile, parallel regulatory, civil, and criminal investigations and prosecutions; and defended small family-owned businesses from environmental regulatory actions and recovered hundreds of millions of dollars in insurance coverage to pay for those responses.   

Bill treats every client’s case as unique. He creates bold litigation strategies to win big and achieve the clients’ business goals efficiently and in a cost-effective manner. He develops creative, proactive, and tailored litigation plans to fit his clients’ business goals based on his 25 years of experience working on a variety of high-stakes cases. Bill also uses an assortment of tools and technologies, including aggressive and targeted pretrial discovery and motions, sophisticated expert witness testimony, and focus groups and mock trials, to develop case assessments and strategies to present his clients’ cases in their best light. Bill’s clients value this approach because it allows for efficient trial preparation by narrowing the issues in dispute, reducing the scope and cost of discovery, and reducing the risks at trial. 

Clients have engaged Bill to take over complex cases going to trial, often from larger law firms. He has tried cases involving scientific issues in federal and state courts and in arbitrations throughout the United States, and is often consulted by other lawyers on the nuances of expert testimony and the admission of evidence at trial. His clients’ cases have been featured in The Wall Street Journal, ABA Journal, BNA Reporters, and major news outlets. For over 15 years, the National Institute of Trial Advocacy has invited Bill to teach trial skills to lawyers from across the country.
