Our Healthcare Assistants

Hi I'm Keili, one of many healthcare assistants working at Marie Stopes' clinics in the UK.

I’m often one of the first people a client sees (during their initial consultation) so I like to make sure they're well informed about the procedures and that they feel at ease with us.

I also do contraception consultations, take medical histories, work in the operating theatre and I look after clients on the ward after their procedure.

I really enjoy being there for people when they really need you. We try to make sure that women are well informed which makes them feel more relaxed. We’re here to advise you and provide a friendly, professional service.
