In Frasier, which character is Martin Crane's live-in caregiver?

“In Frasier, which character is Martin Crane's live-in caregiver?” — Daphne Moon is Martin Crane's live-in caregiver.

Daphne is an English immigrant from Manchester, played by Jane Leeves. Frasier hires her in the series premiere, “The Good Son,” to help Martin with daily activities and physical therapy after Martin's police career ends because of a gunshot wound that leaves him with mobility problems.

Although Daphne is often described as Martin's caregiver, her official role also includes being a physical therapist and live-in housekeeper. Martin quickly approves of her, while Frasier is initially uncertain about bringing a stranger into the household. Her practical nature and close companionship with Martin become central to the show's family dynamics.

Daphne is not Kate Costas, Sherry Dempsey, or Roz Doyle. She later marries Frasier's brother Niles and becomes Daphne Crane. Her relationship with Martin therefore changes from employee and patient-caregiver to daughter-in-law and family member.
