Marilyn Stubbs Cooney resides in British Columbia on Vancouver Island, where she is a signature member of the Federation of Canadian Artists and member of the Arrowsmith Chapter of the FCA.. She is also a founding member of TOSH 10, a group of artists at the Old School House in Qualicum Beach, and a member of the Silk Worm Club dedicated to silk painting.  

Before moving to British Columbia, Cooney resided in Ontario where her first experiences  were as an art and music teacher. Cooney's skills were applied as a graphic artist employed in the greeting and decorating industry. She also freelanced as a graphic artist for a company in Quebec and  a company in Belgium where her work is available in Europe, Asia and North America. Cooney later opened a successful studio/gallery which was ongoing until her move west. As an artist, Cooney incorporates her  graphic skills to produce meticulously explicit watercolours showing the viewer a microscopic intimacy with natural form. Using silk as a canvas and dye as the medium allows the artist to produce work with strong line and the excitement of colour. 

Cooney's work is in collections across Canada, the United States, Germany, Japan and China. The artist has had three successful shows of her work. Two solo shows were at the Lyndia Terre Gallery with the other show at the Chemainus Theater Gallery.

Cooney had her mother as a mentor who studied under Lauren Harris. The artist continues her  education with workshops offered by signature members of the FCA and critiquing her work along with fellow artists.
