September 04, 2025
New York, September 4, 2025— Oliver Wyman, a global leader in management consulting and a business of Marsh McLennan (NYSE:MMC), today welcomes Laurence Birnbaum-Sarcy and John Cusack to its Anti-Financial Crime (AFC) practice.
Laurence Birnbaum-Sarcy joins the firm as Partner. Previously, she was a partner at KPMG LLP in New York, where she specialized in Anti-Money Laundering (AML) and sanctions compliance. Trained as a lawyer with experience in financial services acquired during her time at Société Générale, Laurence assisted many large domestic and international organizations with a variety of projects such as complex, high-profile money laundering and fraud investigations, as well as AFC independent compliance and monitoring matters. Laurence’s expertise spans AML, Office of Foreign Assets Control, and Foreign Account Tax Compliance Act regulatory matters, with a focus on program management, process improvement, operational transformation, and innovation.
“I am excited to join the Oliver Wyman family with its strong reputation in the AFC industry consistent with the expertise and professionalism of its leaders and team members,” said Ms. Birnbaum-Sarcy. “Not only is the Oliver Wyman AFC team’s mastery unquestionable, but they do not settle for status-quo and continuously focus on innovative and tailored solutions best suited to the organizations they serve.”
John Cusack joins Oliver Wyman as a Global Senior Advisor, bringing over 30 years of expertise in financial crime prevention and response, and a wealth of experience from senior roles at UBS and Standard Chartered Bank. In 2019, he founded Financial Crime News, a publication that armed financial crime professionals with relevant materials and tools to support their work. Cusack also served as Chair of the Global Coalition to Fight Financial Crime and was a two-time Co-Chair of the Wolfsberg Group.
“I’m delighted to support Oliver Wyman and its clients in the fight against financial crime by adding to their innovative and impactful approach—building on what we know works, evolving away from what doesn’t, and prioritizing both effectiveness and efficiency,” said Mr. Cusack. “This increasingly relies on collaboration, data sharing, and technology, as well as refining the risk-based approach. Mastering and incorporating these elements is key to future-proofing anti-financial crime programs.”
“We are thrilled to welcome Laurence and John to our team,” said Daniel Tannebaum, Partner and Global Head of the Anti-Financial Crime Practice. “Their track record in the sector and strategic approach to compliance challenges will strengthen our ability to serve clients in a rapidly evolving compliance landscape.”
