O’Quinn Stumphauzer & Sloman is a firm of aggressive and experienced advocates focusing on complex civil litigation, government regulatory enforcement matters, internal investigations, receiverships, whistleblower representation and white collar criminal defense. The trial attorneys at O’Quinn Stumphauzer & Sloman are former federal prosecutors with extensive practical experience.  They have each directed numerous complex cases, from grand jury investigation through jury trial.  Whether it is assisting a whistleblower to report fraud and collect a reward, advising a corporation managing an allegation of wrongdoing, defending an executive accused of fraud, or recovering assets on behalf of fraud victims, our attorneys can help. 

We Prefer to Address Issues Before They Become an Expensive Conflict

In many scenarios, our goal is to help our clients avoid the stress and expense of a conflict.  We believe this is best achieved by helping our clients to minimize the risk of government scrutiny before an investigation ripens into a charged case. We work closely with clients who have discovered indicia of corporate misconduct, and help them quarantine and eliminate the issue before its adverse consequences grow. We customize an action plan, conduct a thorough internal investigation to determine the problem areas, and design a regulatory compliance program. We also work with individual and corporate clients who have already become the subject of a state or federal investigation, with a view to avoiding a sanction or prosecution. We advise our clients not to wait for the government to make a move.  Instead, we take the offensive and move the case in the direction that is best for our client.
