Jennifer Janeira Nagle

Jen Nagle is a prominent member of the firm’s Class Action Defense practice, with nearly two decades of experience defending businesses against consumer protection class actions. Jen currently manages an extensive, nationwide portfolio of consumer class action demands and lawsuits for one of the world's largest retailers, for which she has designed and implemented a portfolio management system that yields results while prioritizing efficiency and consistency.  She has a proven track record of diffusing threatened class action claims before they lead to litigation, securing early-stage wins where cases do progress to court, and otherwise securing favorable decisions and resolutions for her clients.  Committed to a pragmatic, business-first approach to litigation, Jen dedicates herself and her team to learning clients’ businesses and minimizing the disruption that threatened and filed lawsuits can create for their day-to-day operations.

Jen’s experience successfully designing and managing litigation portfolios extends beyond the consumer class action space. She has developed a toolkit for helping clients anticipate and manage litigation trends, prepare strategies for trending or volume litigation, and build processes to both maximize successful resolution of portfolio matters and minimize disruption to clients' in-house attorneys and internal business operations. Jen has successfully revamped litigation portfolios involving class actions, statutory claims, employee disputes, and personal injury complaints, among others underway.

Jen also regularly advises clients outside of litigation in the area of restrictive covenants, including as to compliance with state laws, assessment of hiring and separation risks, and strategic analysis related to enforcement of restrictive covenants.

Jennifer joined K&L Gates in September of 2007.
