Tom is the managing partner of Shook’s Boston office. His litigation practice focuses on high-profile, complex commercial litigation and tort litigation, including class actions, multi-district litigation, and other aggregate litigation throughout the United States. He has extensive experience in complex civil litigation across a variety of industries, practice areas, and geographies, and he has particularly deep experience defending class actions, commercial disputes in the life sciences and health care industries, and in toxic and mass tort litigation. He has represented companies in matters involving complex financial issues, construction and building materials, automobiles, pharmaceuticals, third-party payors, ERISA, RICO, supply and distribution issues, food and beverage labeling, and various consumer products and contracts. Many of these matters have been litigated against the backdrop of criminal and/or regulatory enforcement efforts. Tom has played a lead role at trials in state and federal court in which he has examined fact and expert witnesses, and he has argued appeals. He also has extensive arbitration experience. Tom also maintains an active pro bono practice committed to litigating issues of systemic justice.

Tom has briefed and argued an array of class action issues in cases involving everything from allegedly misleading product labels to claims under ERISA and RICO. He has successfully argued for dismissals of several putative class actions and convinced courts on multiple occasions to strike class allegations from a complaint killing off the threat of class-wide damages. He has developed briefing strategies regarding Rule 23 issues, standing, jurisdictional issues, and preemption that have ended or mitigated the risk of litigation.

Tom’s commercial practice is wide-ranging with a focus on life sciences and health care. He has worked with clients operating throughout the health care supply chain, including matters involving manufacturers (pharmaceutical, medical device, food and beverage and agribusiness), pharmacies, PBMs, GPOs, and health insurers on matters ranging from product liability cases to class actions and False Claims Act litigation. His commercial litigation experience also includes disputes regarding collaboration and development agreements, supply and marketing agreements, real estate transactions and indemnity, earn-out and other post-acquisition disputes. He has also assisted several clients with drafting critical provisions of these agreements. Tom was recognized as an LMG Life Sciences “All-Star” in 2017 and 2018. 

Tom has also been national coordinating counsel in significant toxic tort, mass tort and other complex litigations, many of which have involved parallel government and/or regulatory investigations and enforcement. These matters have involved construction products, pharmaceuticals, devices, industrial chemicals, and agricultural products, among others. He has had lead responsibility for developing company conduct defenses, crafting legal issues and motion strategy, and plaintiff work-up. Tom has collaborated with clients to develop strategies for early resolution of matters through both motion practice and focused settlement efforts, and has experience with selective settlement/litigation strategies. He has successfully coordinated large matters, working with co-defendants in and outside of joint defense relationships. Tom regularly provides strategic counseling and risk management advice to clients regarding product-related risks, deal-related due diligence, and is experienced in different stages of corporate crisis management.

Tom is a recognized thought leader in the area of complex litigation, presenting frequently on class actions and federal jurisdictional issues.  

Before joining Shook, Tom was a partner for about a decade at a large international law firm in Philadelphia. Today he divides his time between Boston and Philadelphia.
