From 2018 to 2021, Wilson served as chair of the American Bar Association’s (ABA) Mergers and Acquisitions Committee, the largest group of its kind in the world. As the creator of the Committee’s influential M & A Deal Points Studies and founding co-chair of the ABA’s Market Trends Subcommittee, Wilson is widely recognized for his thought leadership that continues to shape M&A. And to promote experiential learning by law students in real-world M&A, Wilson founded “The MAC Cup,” the Committee’s national mock M&A negotiation tournament.

Wilson is also a founding co-chair of the University of Texas Mergers and Acquisitions Institute, the US’s leading private company M&A conference since 2005; the founding chair of the International Financial Law Review/Inter-Pacific Bar Association’s Asia M&A Forum in Hong Kong (2005 to 2020), Asia’s leading M&A law conference; and founding chair of the Dallas Bar Association’s Mergers & Acquisitions Section.

Wilson’s leadership extends to diversity in the legal profession, with several transformative “firsts,” including founding/cofounding the National Asian Pacific American Bar Association’s:

• 50×25 Initiative (to have 50 Asian American general counsels (GCs) in the Fortune 500 by 2025)
• Pipeline Program (to curate and cultivate senior Asian American in-house counsel who are “ready soon” to become Fortune 1000 GCs)
• Partners Committee
• Best Lawyers Under 40 Award.

He is also a founding co-chair of the Texas Minority Counsel Program.

From 2010 to 2023, Wilson taught M&A as an adjunct professor of law at Southern Methodist University Dedman School of Law. He is also a member of (and served in various leadership roles at) the New York-based Committee of 100.

Wilson is a co-founder of The Alliance for Asian American Justice Inc., a national coalition of law firms and Fortune 1000 GCs working to stand up for victims and prevent future acts of anti-Asian violence. In its first two years, the Alliance delivered more than $10 million in pro bono services to victims across the country, including a groundbreaking lawsuit against the San Francisco District Attorney, who was later successfully recalled and removed in 2022.
