Katie Erno is an associate in Crowell & Moring’s Labor & Employment Group. Katie represents companies in a wide range of complex commercial disputes, with a focus on employment litigation and counseling. 

Specifically, Katie litigates a variety of wage and hour claims, class actions, discrimination and harassment claims, shareholder disputes, and issues related to corporate governance. She has deep experience in all stages of litigation, from drafting and challenging complaints, fact and expert discovery, drafting and arguing discovery and dispositive motions, trial, and appeals. Her cases range from single-plaintiff disputes to class actions and complex litigation involving large liability exposure in the context of high-profile bankruptcies. Katie enjoys learning the intricacies of her clients’ businesses and tailors her litigation approach with her clients’ ultimate business objectives in mind.

On the counseling side, Katie routinely investigates and advises clients on a variety of pre-litigation employment-related issues, including wage and hour and discrimination and harassment complaints, employee discipline and termination, employment policies and practices, employee mobility, and non-competition issues. Katie works with employers to build compliant and defensible practices in the first instance so that they can avoid litigation whenever possible.

Katie graduated cum laude from New York University School of Law in 2009. She graduated cum laude from Boston College in 2004, earning her B.A. in Hispanic Studies and Communications.
