Mr. Williamson actively supports the Firm’s commitment to pro bono representation. Mr. Williamson first-chaired a AAA arbitration pro bono on behalf of a non-profit organization that fosters at risk families and children against an architect and mechanical engineering firm over mold and humidity issues at a housing facility for the at risk children. The arbitration resulted in a significant settlement for the non-profit client.

He is currently involved, along with a consortium of law firms, in the pro bono representation of Indian welders and pipefitters illegally trafficked from India to the United States in the wake of Hurricane Katrina and Rita in the nation’s largest-ever labor trafficking lawsuit, obtaining a historic settlement valued at over $20 million as well as apologies from the perpetrators of the scheme to its victims. The consortium of cases were named by the American Lawyer as the 2015 “Global Pro Bono Dispute of the Year Award” and the firms received the American Lawyer’s 2015 Grand Prize “Global Citizenship Award.” He has also undertaken numerous adoptions through the Grandparent Adoption program and litigated a variety of pro bono wage claim cases.
