About Us

Affiliations

In order to provide clients with the most comprehensive range of services possible, Armstrong Teasdale has established a group of subsidiary organizations as well as key law firm network affiliations, allowing us to provide resources nationwide.

Subsidiaries

Sometimes the issues of our clients require a skill set or technical expertise outside of the legal profession. To provide better solutions to our clients in those situations, we've formed subsidiaries and business units, and have affiliated with other entities to deliver the required services. The beauty is the collaboration between our lawyers and other professionals for the benefit of our clients.

ATGS provides government relations and strategic counsel to advance the business objectives of companies, industry associations and other entities. Our bipartisan team of lawyers, lobbyists and political consultants has a long track record of success helping shape public policy, legislation and regulations on behalf of clients at the federal, state and local levels of government. Contact Partner Jonathan F. Dalton.

ATGS Adviser Compliance offers dedicated compliance services to independent Registered Investment Advisers (RIAs), handling the adviser’s routine compliance issues as well as giving support when immediate and substantive plans and responses for sensitive regulatory matters are needed. Contact Lori Neidel or Matt Kitzi

Other Affiliations

Armstrong Teasdale's other affiliations, including memberships in legal networks, allow us to provide resources for our clients worldwide.

As a member of United States Law Firm Group, with 6,000 lawyers practicing in 19 firms, we can refer clients to firms across the country that meet their specific geographic requirements.
