Sarah R. Marmor

"We’re a new kind of firm practicing the old-fashioned way; we know our colleagues and our clients, and we put our clients' interests first."


Sarah R. Marmor is an accomplished trial lawyer, employment litigator, and client counselor with three decades of experience successfully representing sophisticated clients on many of their most difficult and sensitive issues.  Sarah has tried complex commercial cases and appeals throughout the United States, in state and federal courts throughout the nation. Sarah represents clients in connection with a variety of complex commercial disputes and employment matters.

Sarah currently heads the Firm’s Employment Counseling and Litigation Practice.  Her employment law experience includes advice and counsel on all potential aspects of an employer/employee relationship, including employment contracts and non-compete and related restrictive covenant matters (a particular strength of the firm), discrimination claims, wage and hour issues, background checks, leave policies and law, diversity initiatives. Sarah defends clients before state and federal agencies and courts, and has tried employment contract, discrimination, and ERISA claims to successful verdicts in both state and federal courts. In recent years, she has developed significant expertise in social media law, as it applies to employers and more broadly, and she frequently lectures on this subject as well as on restrictive covenant law.

Sarah’s complex commercial litigation practice includes breach of contract claims, insurance coverage for corporate policy holders, non-compete and related restrictive covenant and intellectual property suits, consumer fraud litigation, antitrust litigation, product liability/mass tort litigation, and veil piercing litigation. Sarah has defended clients in product liability claims involving breast implants, tobacco, asbestos, household products and appliances. She also has represented clients in toxic tort claims involving chemicals and “toxic” mold.  Through this sophisticated products liability practice, Sarah gained significant experience developing scientific defenses to personal injury and property damage claims – particularly in the disciplines of toxicology and epidemiology. Sarah was a member of the team that defended a multinational chemical company in the first and only breast implant class action suit ever certified. Sarah also helped represent the same chemical company in an environmental insurance coverage suit against over 25 insurers in Detroit, Michigan. She helped successfully defend a major tobacco company in a landmark RICO and consumer fraud suit brought by an asbestos trust against the entire tobacco industry.

Sarah has been recognized as an Illinois “Super Lawyer” in the field of Civil Litigation: Defense and is “AV Preeminent” peer review rated by Martindale-Hubbell reflecting the highest peer recognition for both ethical standards and legal ability.  Crain’s Chicago Business selected Sarah as one of the “Notable Gen X Leaders in Law” and Law Bulletin Media repeatedly has recognized Sarah as a “Leading Lawyer.”  A passionate advocate for the arts, Sarah serves as the Vice President of the Lawyers for the Creative Arts and is a Trustee and member of the Executive Committee of the Court Theatre as well as Chair of its Producers Circle. She has successfully chaired major fundraising events for both of these organizations.  Sarah also volunteers pro bono legal services to victims of sexual harassment. She was elected to membership in Chief, an invitation-only private network designed specifically for senior women leaders.

Sarah received her B.A., magna cum laude, from Princeton University and her J.D., magna cum laude from the Northwestern University School of Law.
