MCC Staff

Our staff is here to help you grow as a disciple (i.e. "learner" or "follower") of Jesus! The ministries of MCC are much bigger than the people on this page - Jesus has gifted and called all of us to be on a mission of grace and love with Him! Our staff is passionate about helping you grow in Him and find your place in God's kingdom. Feel free to learn more about each one here, but even better, meet them in person this Sunday!

  • Jason Leist, Senior Pastor

    Jason is in his ninth year on staff at MCC. After graduating in May of 2014 from Covenant Theological Seminary in St. Louis, Missouri, Jason and his wife Sarah moved to Western PA to be a part of the MCC family.

    Jason grew up in mid-west Ohio. After high school, he went to Muncie, Indiana to attend college at Ball State University to study Sociology and Religious Studies. While a student there he was heavily involved in the campus ministry CRU (Campus Crusade for Christ). During that time he met a gal named Sarah, an Elementary Ed Major. Two and a half years later, they got married.

    Upon receiving a Bachelors of Science degree from BSU, and meanwhile sensing God's call to full time vocational ministry, Jason decided to Intern on Staff with CRU for two years at his alma mater. After these two additional years in Muncie, Indiana, the Leists headed out to St. Louis to attend seminary.

    Since coming to MCC, Jason has been lawfully ordained into gospel ministry by the Pittsburgh Presbytery of the PCA (Presbyterian Church in America).

    Jason's wife Sarah works from home. They have three kids: Cooper, Graham, and Delaney. The Leists live in Export, PA and enjoy traveling, watching movies, board games, reading books, eating good food, and hanging out with friends and family.
