nag Gallery was founded in October 2012 by the curator Mark St.John Ellis. In 2014 nag Offsite was created as a subsidiary arts consultancy service taking contemporary and fine art into domestic and commercial environments where the prospective collector / client can purchase a single work of art or engage the services of nag Offsite to install entire areas with newly purchased works. Expertise is also available on the re hanging of an existing collection and advice on how to incorporate art with interior design.

nag Gallery has a defined philosophy which is represented in 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 Gallery also directly represents artists from Japan and Ireland in contemporary bowls and pottery which enhances the nag Gallery aesthetic and thinking in combining functional and non functional art forms.
