Mat Tomezsko creates abstract paintings, public art installations, and community art projects based around participation and everyday visual language. He often includes elements from everyday experience into his work such as spray paint, graffiti, and asphalt shingles to maintain a sense of contemporary, urban life. His work was recognized by the 2017 Americans for the Arts Public Art Network Year in Review for outstanding public art. Tomezsko’s work has been exhibited at numerous art spaces regionally and nationally, including the Crane Arts, Woodmere Art Museum, the Center For Emerging Visual Artists (CFEVA), and Wexler Gallery in Philadelphia; Lillstreet Art Center in Chicago, IL; the Delaware Contemporary in Wilmington, DE; and Thomas Hunter Projects in New York, NY. He has created several notable public art projects including "14 Movements: A Symphony in Color and Words," a mile-long temporary mural installed in downtown Philadelphia during the 2016 Democratic National Convention; "Look Long and Look Good," a series of 30 paintings currently installed along Main Street in Manayunk; and "Flowering Axes," a mural in the 5th Street Vehicular Tunnel underneath the Ben Franklin Bridge.
