Kiarni Olsen

BA (Hons) Anthropology & English
Practice Manager

Kiarni is the practice manager of Dr Urquhart’s consultation rooms in Paddington. She grew up in Grafton, a small town in the Northern Rivers region and moved to Sydney in 2018 to pursue a degree in English and anthropology at the University of Sydney. She is fascinated by the human experience and loves to learn about different cultures and understandings of the world. In her free time you’ll find her at the beach, going to the theatre, trying her hand at sewing or with her nose in a good book. 

After graduating, she began working with Dr Urquhart in 2022, and she quickly found a new passion for helping patients navigate the medical world, hoping to make the process as smooth as possible for those going through a difficult time. Kiarni loves to chat with patients and learn new things about the world from their unique perspectives and she hopes to help destigmatise colorectal conditions by providing a friendly, compassionate and positive experience for our patients.
