Meet the team →05 / For referring counsel
Costello works with attorneys when a client’s matter develops a white-collar, government-investigation, criminal, regulatory, licensing, or other specialized component.
The firm is particularly experienced in situations where proceedings overlap or decisions in one forum may affect another. Costello can consult, serve as co-counsel, or handle a discrete portion of the matter while the referring lawyer maintains the broader client relationship.
