Meet the team →05 / For referring counsel
Civil and business lawyers often call Costello when a client’s matter develops a government investigation, white-collar, criminal, regulatory, licensing, or other specialized component.
Costello can consult, serve as co-counsel, or handle a discrete portion of the matter while the referring lawyer remains involved in the broader client relationship. When civil, criminal, regulatory, or licensing proceedings overlap, the firm can also help coordinate strategy across forums.
