nag as a gallery was founded by the curator Mark St.John Ellis in 2012. In 2014 nag Offsite was established as an Art Consultancy taking contemporary fine art in to commercial and private interiors throughout Ireland and London, including projects in Kyoto, Japan. By working with such companies as Minima, Bultaup and Farrow and Ball, nag Offsite has evolved its expertise in combining gallery presentation with design. nag Offsite offers professional advice with technical installation that introduces art in to the home or enhances the installation of existing works of art collectors and enthusiasts alike. 

nag has a defined philosophy which is represented by its artists who have a commonality in process. There is an obsession for detail, refined execution and finish in the disciplines of drawing, painting, photography, sculpture, sculptural installation and film making. nag also directly represents artists from Japan in contemporary cha wan bowls which enhances the nag philosophy of aesthetics in combining functional and non functional art
