Expert witness, legal consultant and arbitrator, Professor Mark R. Lee provides unmatched proficiency in antitrust, business organizations / corporate governance, and securities regulation. Since 2011 Lee has held the position of Professor-in-Residence and J. Irving Lawrence Senior Distinguished Teaching Fellow at the University of San Diego Law School.

He has consistently helped his clients secure outstanding outcomes while minimizing hours and expenses--frequently without a trial.

“Professor Lee is like the Adam Wainwright of the legal game. He's been winning for years and every time you see him suit up for the opposing team you just know it’s going to be a tough afternoon!” — Justin Shields, Esq. | Global Trade Advisor at EY

Lawyers for both plaintiffs and defendants have retained him in an extraordinarily wide variety of matters. The antitrust litigation has run the gamut from the first claim against a local government to go to trial to distributor terminations to revocation of hospital privileges. The business organization / corporate governance matters include hostile takeovers, freeze-outs, and fiduciary duty disputes. Fraud, private placements, and restricted securities sales number among the securities regulation engagements. His clients especially value his exceptional communications skills, quick grasp of what the litigation requires, and knowledge base built on more than four decades of consulting, teaching and scholarship.

Lee's publications include ORGANIZING CORPORATE & OTHER BUSINESS ENTERPRISES 6th ed. (LexisNexis 2000/updated annually) (with L. Gross), the go-to treatise for advising entrepreneurs, and ANTITRUST LAW AND LOCAL GOVERNMENT (Greenwood Press 1985).

Lee practiced for the Antitrust Division of the United States Department of Justice and the Attorney General of Texas.
