She routinely handles complex cross-border investigations. Ms. Brooker’s practice also includes BSA/AML and FCPA compliance counseling and deal due diligence and significant criminal and civil asset forfeiture matters. Ms. Brooker also has an active pro bono practice.

Ms. Brooker clerked for Judge Diana Gribbon Motz of the U.S. Court of Appeals for the Fourth Circuit and for Judge James Robertson of the U.S. District Court for the District of Columbia. She also worked in private practice as an appellate litigation associate at an international law firm.
