“In complex litigation, smart lawyering, not over-lawyering, is the key to success.”

Kate is a Chambers-ranked litigation partner at the firm focusing on environmental, toxic tort and class action litigation and Superfund and RCRA remediation matters*.  Since joining the firm in 2003, she has developed considerable experience in defending complex toxic tort claims for personal injury, wrongful death, medical monitoring and property damage, in representing potentially responsible parties across the country in CERCLA and RCRA matters, and in litigating federal, state and private enforcement actions under an array of environmental statutes. 

In addition to her litigation and remediation practice, Kate has also been involved for many years in activities involving Total Maximum Daily Loads (TMDLs) for toxic pollutants, advocating on behalf of individual clients and a regional coalition of industrial and municipal dischargers. Through this work, she has been able to develop a detailed understanding of the nuances of the Clean Water Act and the TMDL regulatory program, and the contours of TMDL litigation at the federal and state levels.

Kate was named an American College of Environmental Lawyers Fellow in 2023. She served as the firm's Hiring Partner for three years after chairing its Summer Associate Program for five years.

Outside of the office, Kate guest lectures on toxic torts at the Charles Widger School of Law at Villanova University and has taught Toxic Tort Litigation as an adjunct professor at Drexel University Thomas R. Kline School of Law.  She also serves as the firm’s representative and a Director in the Environmental Law Network and has been actively involved for years in various leadership roles for the American Bar Association’s Section of Environment, Energy and Resources. She has been on the Board of Directors for the Partnership for the Delaware Estuary since 2023, after prior committee involvement.

In her free time, Kate enjoys staying physically active, coaching youth basketball, and spending time with her husband and three children, especially at the Jersey shore.
