Pastor & Family

Each raised in the home of a great man of God, the Mitchells have enjoyed the unique privilege of experiencing ministry from the "inside out" their entire lives. Pastor Robert & Lisa both come from extended families inundated with pastors, preachers, and ministers of all sorts. 

After marrying in the fall of 1990, this dynamic couple spent the next seven years traveling the world in full time evangelism. After that, they launched a new church in the picturesque city of Asheville, North Carolina, where they spent ten years building that congregation by impacting the community. They then spent four eventful years as the Lead Pastors of a multicultural church in the military city of Fayetteville, North Carolina. What God did in those first twenty-one years through the Mitchells' leadership, Apostolic anointing, and vision, was miraculous.

Embracing the pastoral calling to different churches in different cultures, the call of God came once again, directing them to uproot their family and move 1,700 miles to start yet another church. This step of faith further expanded the reach of Christ in the world. 

The true blessings of God have been upon this family, not only in the above-mentioned endeavors, but also in the interim pastorates they have accepted at times, along with the Spanish, Russian, and Ukrainian cultures they have worked with. Many leaders have been raised up, ministers trained, direction/counsel given, and doors opened for new church plants - along with daughter works - under their watch. The Mitchells have ministered at conferences, camps, revivals, retreats, and events of all sizes, and God has done His work by flowing through them. Many describe them as modern day apostles, visionaries, and passionate lovers of humanity.


The Mitchells, along with their three daughters, are now thrilled to actively serve the young congregations of Vertical Church, as the founders and lead pastors. And if the past endeavors of this ministering family are any indication of what the future holds, Vertical Church is one to watch!

Lisa leads the Children Ministry at our South Campus and the Music Ministry at both locations.

Karen Hemmes

VGroups Coordinator

The daughter of a lifelong church planter, Karen Hemmes has always had passion for working with new Christians, especially in the home cell group ministry, which she’s been involved with for two decades. Under her leadership, Vertical’s V-Group ministry has grown to include groups across the metro area – plus a group just for teens and one for young girls, which Karen facilitates in her own home. In addition to V-Groups, Karen sings with Vertical South's praise team, helps with the Welcome Center, and is the administrator for the church’s Facebook pages. She’s the mother of three grown daughters, (Karly, Dana, and Destiny) and very happy grandmother to seven world-class grandchildren (Tyrus, Alexis, Carsten, Dominque, Josiah, Dylan, and Roland).
