About

Vanessa Singh Johannes is a seasoned trial attorney who counsels individuals and corporations on a wide array of civil, criminal, and compliance matters. She offers clients nearly two decades of experience, both as a former federal prosecutor and complex litigator.

For a decade, Vanessa honorably served as an assistant U.S. attorney for the Southern District of Florida, where she tried dozens of jury trials, handled hundreds of criminal and civil investigations, and argued appellate matters before the Eleventh Circuit Court of Appeals. She investigated, indicted, and tried cases involving serious crimes that affected everyday people in the Miami community, large companies, and U.S. taxpayers, including fraud, money laundering, espionage, civil rights, arms trafficking, human trafficking, and murder.

Vanessa’s vast experience as an assistant U.S. attorney lends her unique insight into all phases of government investigations — such as grand jury inquiries, complex search warrants, and mutual legal assistance treaty requests — and reliable knowledge of federal practice in the district. During her tenure, she also developed a close working relationship with federal, state, and local law enforcement agencies, including the U.S. Secret Service, the Bureau of Alcohol, Tobacco, Firearms, and Explosives, Drug Enforcement Agency, Homeland Security Investigations, and the Federal Bureau of Investigation.

In private practice across two major law firms, Vanessa has developed a successful track record handling complex “bet-the-company” cases. She represents companies in an array of civil matters, complex litigation, and crises and assists clients in responding to federal agency inquiries, conducting internal investigations, board presentations, training on relevant laws, and crafting compliance programs to meet legal regulatory and criminal requirements. Armed with her experience as a federal prosecutor, Vanessa also handles complex criminal matters, including those involving the False Claims Act, the Foreign Corrupt Practices Act, wire fraud, and money laundering.

Prior to joining Foley, Vanessa was the co-managing shareholder of a national law firm’s Miami office.

She handled the intake for all PSC matters in our District, which spans and encompasses the counties between Key West, FL to Fort Pierce, FL.

Her job required her to keep abreast of computer hacking and intellectual property ("CHIP") updates, case law, and changes, and to attend trainings at the NAC on technological advancements that affect online criminal behavior. She worked closely with the FBI and HSI, and ICAC (Internet Crimes Against Children) task force, special agents, USMS, and local law enforcement in South Florida to investigate and prosecute all federal crimes against children.
