She comes from a notable bridge family, her parents, Pat and Nico Gardener, both having played for Britain. She ran the London School of Bridge, which her father had founded in 1952, for many years. She still teaches bridge.
In 1983, she took part in a televised match arranged by the BBC between teams representing Britain and the United States. The British team was Tony Priday, Claude Rodrigue, Nicola Gardener (as she then was) and Pat Davies. The US team was Neil Silverman, Matt Granovetter, Jacqui Mitchell and Gail Moss. The British team won by 32 international match points over 78 deals in seven sessions. The match subsequently formed the basis of a book, in which she was described as follows: "...one of the finest women players in the world. Not only is she an excellent technician – truly, the daughter of her father Nico Gardener – but is equally aggressive and imaginative both in bidding and defence."
She was awarded the MBE in 1995 for her services to bridge. In 2015 she was one of the first two winners of the English Bridge Union's Diamond Award, introduced to recognise players who have "represented England (and earlier Great Britain) with distinction over a long period".
Outside bridge she has worked as a business administrator, but has recently been training to be a healer. She married Jonathan Smith in 1983; they have two children.
