Seth Darmstadter is the Managing Partner of M&R’s Chicago office and the firm’s nationwide Class Action & Complex Litigation Practice Leader. He is an innovator who works as a strategic partner, delivering solutions-based approaches to law and commerce that allow entrepreneurial companies to effectively navigate crowded and competitive industry landscapes.

Many of Seth’s clients are industry disruptors that relish his fierce loyalty, comprehensive vision, forward thinking and enthusiasm. These traits make him a trusted collaborator and consultant—one who provides advice and counsel not just about law, but business operations as well. Seth is particularly proud of his work as former General Counsel for Outcome Health, where he was an essential part of the turnaround team of senior executives who shepherded the company through a well-publicized crisis involving allegations of systematic wrongdoing by its prior leadership.

An experienced and accomplished commercial litigator, Seth represents clients in state and federal courts, as well as at arbitration (commercial and labor). Over the years, he has favorably resolved a range of cases, including partnership, commercial real estate, business and contract disputes; unfair competition claims; breach of fiduciary duty and restrictive covenant litigation; insurance coverage matters; employment conflicts; and tort actions. Seth is known for securing early-stage injunctive relief and claim resolution.

A prolific writer, several of his restaurant reviews have graced the pages of Chicago Lawyer magazine. Seth also regularly authors articles for The Chicago Daily Law Bulletin and has spoken publicly on several interesting topics, including a presentation to GCs at the Consumer Electronics Show in Las Vegas regarding optimization of the legal spend.
