Upon graduating law school, Laurence joined LeBoeuf, Lamb Leiby & MacRae as an associate of the San Francisco office. There he worked on complex litigation matters, including the hostile takeover by British American Tobacco US of Farmers Insurance Group. He later represented both plaintiffs and defendants in securities fraud claims and in business tort litigation. He gained additional trial experience representing the trustee and creditors in federal and state law insolvency claims.

Laurence has resided in Buenos Aires since 1993. From 1993 to 2001, he worked with Muñoz de Toro & Muñoz de Toro, a boutique specializing in corporate finance and mergers and acquisitions, eventually becoming a partner and achieving a ground-breaking precedent for US lawyers in Argentina. Throughout the years, Laurence advised issuers and underwriters on registered and exempted offerings of Argentine corporate debt, equity and convertible securities.

In the context of Argentina’s default, devaluation, economic collapse and recovery, Laurence adapted his experience in two legal systems to benefit foreign investors. His practice currently extends to advising companies on acquisitions, finance, funding and repatriation of investments, and risk management.

Laurence is recognized as a ‘Notable Practitioner’ for his M&A/Corporate work in Chambers and Partners Global Guide, 2014.
