The firm has a strong track record of trial work, victories on pretrial motions, successful sentencing advocacy, and negotiations to resolve cases short of a trial.

Congressional Investigations: Understanding the Congressional investigation process from their previous work within government,  KaiserDillon guides clients through communicating with the investigating committee; evaluating how to respond; providing documents or testimony, as appropriate; preparing to testify, as appropriate; litigating if necessary; and managing the legal, political, and other implications of the investigation and subsequent findings.

Campus Disciplinary Defense:  KaiserDillon attorneys represent students at universities across the country accused of violating Title IX; they have written on Title IX in national publications, taught other lawyers how to defend these cases, and given presentations to Title IX coordinators about how to set up fair processes at their schools.
