Lesley Groff served as Jeffrey Epstein's longtime private executive assistant for approximately 20 years, primarily based in New York, where she handled travel, appointments, scheduling, and day-to-day office operations. She has been named in Epstein-related lawsuits and court documents, including as an unindicted co-conspirator in the 2008 non-prosecution agreement, with allegations that she facilitated aspects of his sex trafficking and abuse activities. Her attorney, Michael Bachner, has denied any involvement in criminal conduct, stating she worked in Epstein's business office alongside attorneys and other executives. Groff resides in New Canaan, Connecticut, and was reported to be 58 years old around 2019. Her name appears in unsealed Epstein files, including a forwarded email to Epstein about a 'very intimate' Hillary Clinton fundraiser hosted by Howard Lutnick at Cantor Fitzgerald. She has been described in media and investigative reports as a key figure and alleged scheduler potentially holding knowledge about Epstein's client list and operations. While no criminal charges have been filed against her, her long tenure and proximity to Epstein's activities have placed her under scrutiny in ongoing investigations into his network.
