Natasha Vij Greiner, former Director of the US Securities and Exchange Commission (SEC)’s Division of Investment Management, will join WilmerHale as chair of the firm’s Investment Management Practice.
Greiner brings over 24 years of distinguished experience at the SEC, including senior leadership roles across four agency divisions. Her arrival deepens WilmerHale’s strategic commitment to its Investment Management platform and complements WilmerHale’s premier Securities and Financial Services Practice, which includes former Directors of the Divisions of Enforcement and Corporation Finance, as well as Chief Counsel and Chief Litigation Counsel of the Division of Enforcement.
“Natasha’s insight into the SEC’s regulatory landscape is unparalleled,” said Anjan Sahni, WilmerHale’s Managing Partner. “Her experience and leadership will be invaluable to our clients as they navigate an evolving regulatory environment. Natasha’s presence meaningfully enhances our capabilities and reflects our ongoing investment in talent that positions us at the forefront of the investment management sector and securities industry.”
“Natasha’s profound understanding of public and private fund issues and substantial experience with complex regulatory and examination matters, make her an exceptional addition to our team,” said Stephanie Avakian, Chair of WilmerHale’s SFS Department.
Reflecting on her decision to join WilmerHale after a notable career at the SEC, Greiner said, “WilmerHale is the ideal place to leverage my experience and knowledge to advance clients’ strategic goals. The firm’s collaborative culture, strategic vision, and dedication to client service make it the perfect place to continue making a meaningful impact. I am excited to join such a talented team and contribute to the firm’s ongoing success.”
Greiner began her SEC career in 2001 as a broker-dealer examiner. In her 24-year career at the agency, she held multiple roles, most recently as Director of the Division of Investment Management from March 2024 to July 2025, where she led a team regulating the $129 trillion asset management industry and oversaw major rulemaking initiatives. She previously served as Acting Co-Director and Deputy Director of the Division of Examinations and National Associate Director of the IA/IC examination program, which covers the Private Funds Unit.
Her other previous roles included serving as Acting Chief Counsel and Assistant Chief Counsel in the Division of Trading and Markets, where she advised the Commission on legal and policy matters related to rules governing market participants and securities market operations. Additionally, she held positions within the Division of Enforcement—including the Asset Management Unit—where she investigated potential violations of federal securities laws and litigated cases in both federal district court and administrative proceedings.
Greiner earned her BS, cum laude, from James Madison University in 1997 and her JD, from Catholic University School of Law in 2001.
She will be resident in the firm’s Washington DC office and joins January 2026.
