Prue O'Day established Anderson O'Day in 1971 with partner Don Anderson after gaining considerable experience working for contemporary print publishers and old master print dealers. Their enterprise selling original prints was so successful that they became print publishers.
While this side of the business continued to thrive under Don Anderson, in1986 Prue opened the Anderson O'Day Gallery in Portobello Road to show paintings and sculpture. During the years of the Portobello Contemporary Art Festival, which she co-founded, the area became a magnet for art and design galleries. The Anderson O'Day gallery acquired an international reputation, recognised for discovering emerging talent.
In the late 90's, inspired by the advancing new millennium, Prue and Vanessa Branson launched The Wonderful Fund, a five year project on behalf of sixteen fund members who enjoyed shared ownership of the works. The sums involved were modest. The collection of more than sixty artists is a testament to this unique moment, recording the pulse of its time with a reach that is broad, international and of the highest quality.
Prue continued her work as an Independent Art Advisor to corporations building significant collections for Ernst & Young, Marsh and WestLB. Major commissions included collaborations with Sol LeWitt and Norman Foster at Tower Place, Rebecca Warren and Renzo Piano at Central Saint Giles, HM Treasury, Whitehall and the first site specific commission by Conrad Shawcross at Unilever.
In the early 2000's, Prue began working with Wendy Fisher, now President of the Guggenheim Foundation, to help with her collection. This led her to focus on advising and curating for a small number of private collectors, including the ISelf Collection and Alex Petalas who then went on to open The Perimeter.
Prue chaired The Showroom from 2006-2013, guiding its relocation to a central London space and achieving financial stability for the organisation. From 2009-2013 she mentored Glasgow Museum of Art for the Art Fund International purchasing scheme. Prue served on the board of the ICA from 2014–2020. She was a guest lecturer and external examiner on the Sotheby's Institute MA and a regular contributor to Professional Development courses at London art schools.
Prue is no longer taking on work with private collectors but is actively involved in mentoring and advising artists, gallery colleagues and public institutions including the Advisory Acquisitions Committee for The Hepworth Wakefield. She is a visiting tutor at TEAR (Tracey Emin Artist Residency) and is collaborating with Freeny Yianni on the estate and legacy of Jane Harris, who was represented by Anderson O'Day Gallery at the beginning of her career.
