John Walker studied at the College of DuPage in Wheaton IL and the American Academy of Art in Chicago IL. Upon graduation he worked at Feldkamp/Malloy before becoming a staff illustrator at Higgens Hegner Genovese and later a freelance illustrator with Frank Lux and Associates. For over fifteen years he has worked from his own studio creating artwork for a diverse group of advertising and publishing clients including National Geographic, The Bradford Exchange, McDonalds, Warner Brothers and Random House.

John has always painted for personal satisfaction,as time and obligations allowed, but the past few years have seen a greater share of his time and energy devoted to creating fine art. He has recently returned to exhibiting his work in public and has taken first place honors in several shows. His painting Rose won a First Place Award at the 2010 Alliance of Fine Art’s Best of the Best exhibit.

He is a member of The National Society of Casein and Acrylic Painters, The Downers Grove Artist's Guild and the DuPage Art League.
