About MadKat Studios

Fine art paintings and photography by Derry, NH artist John Sweeney. He loves to explore the World in vivid colors using oils, watercolors and photography. What it is about a certain combination of colors, shapes and shades that tickle the imagination? John is a person in long term Recovery from Alcoholism and discovered the benefits of creating art as a tool to battle the disease and combat depression and anxiety.

‘For me Art is a science of self discovery. Why and what is it about a certain combination of shapes, colors and shades that produce an unforgettable emotional response. There is no finish line to the depths of this self discovery because just as there are an infinite number of shapes, colors and shades there is also and endless supply of inspiration.’

~John R. Sweeney Jr.
