Parker Button Company was established in Pittsburgh, Pennsylvania, in 1915 by Joseph Korpacy. After his father's retirement, son, Howard Korpacy, took over the business in the famed Pittsburgh Landmark, the Jenkins Arcade.

Eventually, "Parker's" as it is called by its loyal customers was moved to the Bennedum Trees Building where it stayed until it was purchased in 1992 by the Clarissa Boutique.

Both Clarissa Boutique and Parker Button Company resided in downtown Pittsburgh in the Warner Centre until 2004, when they both moved to their present location on Pittsburgh's "Southside" at 1700 East Carson Street.
