Cimberly Espinosa worked as a legal assistant at J. Epstein & Co. starting in October 1996 and later served as an executive assistant to Ghislaine Maxwell for six years, assisting in the management of Jeffrey Epstein's estates, including preparing trees for shipment to his private island. She testified as a defense witness during Ghislaine Maxwell's 2021 sex-trafficking trial, stating she never observed any misconduct by Maxwell despite working closely with her.
