Mike Greco is a partner in the Denver and Philadelphia offices and a member of the Firm’s Employee Defection and Trade Secrets Group. He litigates and provides counseling nationwide to employers concerning legal claims and issues arising from the movement of employees between competitor firms.

These issues include: covenants not to compete, non-solicitation and non-disclosure agreements, unfair competition, employee raiding, trade secrets, duty of loyalty, Computer Fraud & Abuse Act, Economic Espionage Act, and state trade secrets and unfair competition statutes.

Mike has prosecuted and defended hundreds of employee defection and trade secret  matters, obtaining and defeating injunctive relief in at least 35 different state and federal courts, in addition to dozens of arbitration actions before the Financial Industry Regulatory Authority.

His experience includes representation of clients in the securities brokerage, health information technology, medical practice, computer sales and distribution, commercial window washing, personnel placement, online retailing, insurance brokerage, insurance, publishing, direct response television, radio, institutional food services, and freight forwarding industries.

In addition to litigating, Mike assists corporate clients in developing and implementing coordinated local and/or national programs to protect their competitive assets against employee defection, and to minimize risks that arise when hiring employees from competitors.

His practical knowledge of how courts have treated various restrictive covenants enables Mike to help employers draft appropriately tailored restrictive covenants.

Mike was included in the 2013, 2014 and 2015 edition of Pennsylvania Super Lawyers. He was also recognized in Pennsylvania Super Lawyers – Rising Stars in 2005, 2006, 2007 and 2010. He is the co-editor of the firm's Non-Compete and Trade Secrets Blog.
