Keith runs the Grinter Glass studio in Whangarei. His artworks include painted and blown glass as well as painting and sculpture. His fascination with modernist painting has provided inspiration for his glasswork. He uses the glass shard pick-up technique and mixtures of coloured frits to create the unique patterns in his glasswork. His artworks are often based on blind contour drawings made while walking. This is a technique that he developed whilst studying for his Master's degree as a means to investigate the everyday.
