Armstrong Teasdale attorneys represent organizations, departments and individuals across public/private sectors and industries in ethics and professional responsibility matters.

Whether as part of an internal investigation, confidential disciplinary process, the development of internal controls or litigation, our attorneys have the experience to advise, consult and represent parties in various federal and state jurisdictions. Our attorneys include former chief disciplinary counsel, state Supreme Court disciplinary committee members, city solicitors, public officials and judges. Our clients, often in government, municipal or professional services, benefit from our robust, cross-functional experience in Litigation, Governance and Compliance, Medical Malpractice, Tax and Securities Regulation and Litigation to  represent parties charged with enforcing, and parties alleged to have violated code of conduct and ethical obligations.

We aim to provide transparent, clear guidance in each interaction and regularly counsel clients proactively in avoiding violations by implementing thorough compliance programs. We also provide insight and interpretation of guidance in specific applications, as well as offer comprehensive ethics training and Continuing Legal Education seminars.

Our skilled team of attorneys, including a fellow of the American College of Trial Lawyers, has been recognized for its discretion in the face of complex matters, as well as a commitment to civility and professionalism.

Attorneys in our Ethics and Professional Responsibility practice also represent physicians across disciplines, pharmacists and other professionals in state and federal matters where their reputations or licenses are at risk. We skillfully advocate on behalf of our clients before various state licensing boards and disciplinary bodies in response to complaints filed against them.
