In October 2018 four parishes, Saint Joseph Parish in O'Hara/Fox Chapel, Saint Juan Diego Parish in Sharpsburg, Saint Padre Pio Parish in Blawnox/Harmar, and Saint Scholastica Parish in Aspinwall were combined to form the Lower Allegheny Valley Grouping of Parishes.
In July 2021 these parishes were formally merged to form the new Christ the King Parish with Fr. Dale DeNinno as Pastor and Fr. William Siple as Parochia Vicar. Masses are offered in six churches: Saint Edward Church in Blawnox, Saint Francis Church in Harmar, Saint Joseph Church in O'Hara, Madonna of Jerusalem Church in Sharpsburg, Saint Mary Church in Sharpsburg, and Saint Scholastica Church in Aspinwall. The administrative center is located at Saint Joseph Church on 342 Dorseville Road.
