Kirsty Millar, portrayed by
Kiruna Stamell, made her first appearance on 11 January 2023. She is introduced as a receptionist at the Mill Health Centre following the dismissal of former receptionist
Valerie Pitman (
Sarah Moyle). In her first scene, she meets with
Ruhma Carter (
Bharti Patel), who she has known for years due to working with her at St. Phils Hospital. Ruhma has high praise for Kirsty, informing the staff at the Mill how experienced she is. Speaking of her first episode, ''
What's on TV'' wrote that Kirsty would divide the existing staff due to her "forthright manner". On her
BBC profile, Kirsty was described as an "organised, loving, opinionated" character that "doesn't suffer fools". It also stated that her reason for coming to the Mill was to seek a new life. ''What's on TV
also teased the imminent arrivals of her husband and son, Rich (Richard Atwill) and Ollie (Isaac Benn). Inside Soap'' also hinted that Kirsty and fellow receptionist
Scarlett Kiernan (
Kia Pegg) would have a workplace dispute when the pair "rub each other up the wrong way". However, a friendship between the pair is eventually developed when Kirsty invites Scarlett to live with her. Stamell appeared on the BBC topical series
Morning Live in March 2023 to talk about her time on
Doctors, where she said that she was grateful to be given a character backstory that did not revolve around being disabled. Presenter
Gethin Jones remarked that Kirsty does not reference her dwarfism, which Stamell replied that she is thankful for. She felt that because Kirsty's family and colleagues would be used to her condition, there would be no point in talking about it since it is part of her everyday life. Since Stamell has an Australian-influenced accent from her time living there,
Sam Quek asked how she had learned the
Brummie dialect. Stamell recalled listening to audiobooks narrated by
Jess Phillips and
Alison Hammond and said that she was influenced by their accents. She struggled to pick up the accent at first, but began to feel more comfortable using it the longer she had stayed in the role. Alongside Atwill and Benn, Stamell was nominated for the Best Family accolade at the
2023 British Soap Awards. Stamell departed the role in 2024 and Kirsty's final episode was broadcast on 25 September 2024. Despite
Doctors being confirmed to end in December 2024, Stamell's departure prior to finale was not announced to the public and was instead left as a surprise to viewers. Following her exit, Stamell said that her favourite storyline was Kirsty's romance with
Dave Burns (Gareth Berliner). Berliner is Stamell's real-life husband and she revealed that her favourite scene was one that never aired, of Dave trying to seduce Kirsty with French cuisine when Berliner dropped a baguette. ==Nina Bulsara==
