Who Is Tiffany Anne Keigley?
Table of Contents
Tiffany Anne Keigley (CRD# 4507001) is a former broker and investment advisor with 17 years of experience in the securities industry. She spent the majority of her career—approximately 15 years—at Morgan Stanley in Tulsa, OK, and previously worked at Citigroup Global Markets Inc. Keigley is also known by several other last names, including Headly, Robertson, and Williamson.
Keigley is now permanently barred from the securities industry by both FINRA and the Oklahoma Department of Securities following allegations of unauthorized use of client funds and failure to cooperate with regulatory investigations.
Why Is Tiffany Anne Keigley Under Investigation?
The primary reason for the investigation and subsequent regulatory actions against Keigley centers on unauthorized disbursements from a client’s brokerage account. Over a seven-year period (from July 2017 to October 2024), Keigley allegedly used a client’s account to pay personal expenses, withdrawing more than $108,440.20 without the client’s knowledge or permission.
Additionally, Keigley failed to comply with requests for documentation during FINRA’s investigation—an action that itself is a violation of industry rules. The seriousness of these allegations led both FINRA and Oklahoma regulators to issue permanent bars against her participation in the securities industry.
