James Mongrain (b.) is a Seattle-area glass artist. He was educated at Moorhead State University in Minnesota, then studied glassblowing at Massachusetts College of Art and Design and the Appalachian Center for Crafts. Mongrain lives in Everett, Washington and operates a studio in Mukilteo at a former salmon smokehouse. He is considered one of the leading artists of the studio glass movement in the Pacific Northwest, and has unique mastery of Venetian goblets, combining the techniques of using a mold and blown glass on the same piece.
