National law firm Armstrong Teasdale LLP has announced that its subsidiary, AT Government Strategies (ATGS), has acquired Adviser Compliance Services LLC (ACS), a consultancy specializing in regulatory compliance and government relations services for registered investment advisers of all sizes across the United States. The combination expands the existing capabilities of ATGS—including public affairs, lobbying and government supervision—by introducing a dedicated compliance function tailored to the needs of the investment adviser community, operating in the industry regulated by the US Securities and Exchange Commission and its state counterparts.

As part of the transaction, Lori Neidel, founder and managing member of ACS, joins ATGS as Vice President of Compliance Services. With more than 25 years of experience in law and regulatory consulting, including a prior role as Chief Enforcement Counsel at the Missouri Securities Division, Lori brings extensive subject matter knowledge and leadership to the expanded compliance team. Neidel, a Missouri licensed attorney, will also join Armstrong Teasdale as Counsel in its Securities Regulation and Litigation Group.

Joining Lori at ATGS are Scott Snipkie and Jennifer Henley, who will serve as Director of Adviser Services and Compliance Services Manager, respectively.

“Lori and her team joining us at ATGS is a real win for our group,” said Matt Kitzi, Managing Attorney for Armstrong Teasdale’s Jefferson City office and Vice President for ATGS, who worked with Neidel when he served as Missouri’s Securities Commissioner. “Lori and her team are leaders in their field, and their addition to ATGS allows us to significantly enhance our services to existing investment adviser clients while expanding our compliance and regulatory work to a truly national level.”

The new compliance team serves both federal covered and state registered investment adviser firms and representatives operating in 26 states and will be backed with the full support and resources of Armstrong Teasdale, an Am Law 200 firm with its own national footprint.

“Joining Armstrong Teasdale and AT Government Strategies allows us to offer even greater value to even more investment advisers across the country,” said Neidel. “This move strengthens our ability to provide much needed guidance to firms as they navigate an increasingly complex regulatory environment, while expanding our team and adding broader institutional resources and a greater platform for growth.”

AT Government Strategy’s acquisition of Adviser Compliance Services is effective as of Aug. 1, 2025.
