Jane Norberg, former head of the whistleblower office at the Securities and Exchange Commission (SEC), has joined D.C. law firm Arnold & Porter as a partner.

Norberg’s practice will focus on helping companies navigate whistleblower issues, according to a press release Monday.

As part of her new role, she will be “counseling companies seeking proactively to assess their exposure to whistleblower allegations and, in the case of specific allegations, assisting the company in guiding its response and defense,” Arnold & Porter said.

Norberg was chair of the SEC’s Office of the Whistleblower for the past four years until she resigned in April. Before taking the helm of the office, she served as deputy chief for four years.

A permanent replacement to lead the office has not yet been named by SEC Chair Gary Gensler. The office’s deputy chief, Emily Pasquinelli, is serving as acting chief.

Norberg was in private practice before she worked at the SEC, focused on executive compensation and employee benefits. She also served as a special agent in the United States Secret Service for five years.

“I was drawn to Arnold & Porter’s deep bench in the Securities Enforcement and Litigation, Employment, and White Collar and government investigation areas,” she said in the press release. “I look forward to joining these professionals in assisting clients to anticipate and proactively address whistleblower issues when they arise and to mitigate the potential legal and reputational consequences.”

Norberg has a law degree from St. John’s University School of Law and a bachelor’s degree from Bloomsburg University of Pennsylvania.
