After College he worked for 5 years as a free-lance illustrator whilst also painting and exhibiting. As a result of the volume of illustration and graphic design work he was being asked to undertake, he set up an advertising, marketing and design consultancy in Dundee in 1980 which he ran until 1996, returning to painting full time in 1997. 

Perhaps more than his immediate contemporaries Jack seems to have embraced the extraordinary variety of inspiration inherent within Scotland, and whilst remaining true to a proud lineage, has developed a powerful and effective distillation of his own encompassing still life, figurative and landscape work. Whilst technique and application of paint may vary with subject, each work shares the mature handling and vibrant, sensuous palette so associated with the artist.

Jack now works from his studios in Fife and the South of France.

Jack studied at Duncan of Jordanstone College of Art 1970-1974 with a Post Graduate year in 1975. He also studied at Hospitalfield House, Arbroath under Peter Blake in the summer of 1973.
