Olivia Nicholson (known as Liv, she/her) lives with partial hypopituitarism, which results in short stature (4ft 10"), vasopressin deficiency, and growth hormone deficiency. Managing this condition means prioritising rest, strength training to maintain muscle mass, balancing medication, and staying positive and energetic, even though many with hormone deficiencies can feel fatigued or low in mood.

Liv’s main career has been as a PA, working for a decade with multinational firm EY before joining the Cambridge University Sports Service, where she has spent the last 7.5 years in Bookings & Finance. She is recognised for her organisational flair, excellent communication skills, and her ability to bring fun and positivity to every environment. Alongside this, Liv is building her modelling career as the original Petite Pocket Rocket. At 4ft 10", she champions true petite representation, with her first campaign being a jeans shoot for Dewey Jeans in July 2025.

Her proudest achievement has been serving as an Ambassador for Hearing Dogs, appearing on BBC1, Radio 1 and in magazines, where she also met HRH Princess Anne and then-Prime Minister David Cameron.

Liv’s ambition is to model for commercials and fashion, especially petite clothing, proving that mature, petite women deserve visibility. She is passionate about fitness, fashion, beauty trends, and interior design.
