Tara MacMillan

Partner, Chief Professional Officer & Regional Head, Americas
Our People/Tara MacMillan

As Nardello & Co.’s Chief Professional Officer, Tara MacMillan oversees the quality of the firm’s investigations globally and, as Regional Head of the Americas, she directs its work in that region. Tara has extensive experience managing complex litigation support investigations, due diligence exercises, and compliance reviews, both in the US and internationally.

Tara manages international anti-corruption compliance relationships for several multinational clients. She has conducted investigations and helped clients develop their compliance programs for key suppliers, distributors, and third-party representatives. Among other specific services, Tara helps strengthen clients’ review processes, customize questionnaires, or tailor reporting elements for employees and agents. Her casework includes investigating instances of fraud, embezzlement, bribery, and kickbacks, including those stemming from whistleblower allegations and those related to the Foreign Corrupt Practices Act.

Tara also has extensive experience managing due diligence investigations. On behalf of firms interested in expanding into Latin America or Europe or considering international acquisitions, she has led investigations to pinpoint potential risks—such as corruption and organized crime—by uncovering ownership interests and political and governmental affiliations. Tara’s knowledge, experience, and research prowess have contributed to successful defenses in corporate takeovers, proxy contests, and tender offers.


Representative matters
  • Tara led the redesign of an international manufacturing company’s compliance program covering several hundred intermediaries. She and her team conducted on-site compliance audits of the vendors categorized as high risk, located throughout Asia, Eastern Europe, and Latin America.
  • To identify customers who could serve as witnesses on the client’s behalf, Tara led rigorous open-source research for a client faced with product liability lawsuits in several jurisdictions. After reviewing traditional media, regulatory filings, and social media platforms, and contacting affinity groups, Tara’s team identified more than 200 potential witnesses. Through supplemental investigation and interviews, the number was further reduced. Her team presented a vetted group of potential witnesses to outside counsel in preparation for trial.
  • Tara headed an in-depth open-source investigation of investors for a consumer products manufacturer that believed itself to be the target of an organized effort by short sellers to suppress its stock price. The research revealed that several investors who claimed to have no links to the short-selling community had associations and work history with certain high-profile and activist short sellers. The research also determined that several subjects – in an attempt to camouflage their online identifies by purporting to be unique users – created multiple internet identities/handles with which to make specious allegations. The findings helped inform the client’s public relations strategy.
