Sherri ter Horst is the manager and concierge of the Chiron Building. She is an anti-augmentation supporter, and as such, is hostile towards Adam Jensen due to his recently-received augmentations and employment at Sarif Industries.
Ter Horst is contacted by Jensen about replacing a broken mirror in his apartment. She claims that she is still waiting for the new mirror to arrive, when in fact it has been waiting in storage for almost four weeks. It is unclear why she refuses to replace Jensen's mirror, but it could be due to her bias against augmented people.
