Greg Horn, Pastor & Head of Staff

The Rev. Gregory A. Horn has been PCUM's pastor since early 2009. Greg is a graduate of Stanford University in California and Union Theological Seminary in the City of New York, where he was recognized for his preaching and promise of future excellence in parish ministry. 

Since 1991 he has led four Presbyterian congregations through periods of sustained renewal, vitality and growth. Greg was ordained and started his ministry as pastor of the Fewsmith Memorial Presbyterian Church in Belleville, New Jersey, a transitioning, working class community on the border of Newark. From 1995 to 2000 he led the vibrant First Presbyterian Church of Englewood in south Denver, Colorado. From 2000 to 2002 Greg served as Director of Operations for a New York City agency that employed recently-incarcerated felons and housed homeless persons living with HIV/AIDS.  Before coming to PCUM, Greg served from 2002 to early 2009 as Senior Pastor/Head of Staff at the First Presbyterian Church of Cranford, New Jersey, leading that 700-member congregation through an exciting period of growth and revitalization. 

Since 2005 he has also served on staff at Auburn Theological Seminary in New York City, advising Presbyterian students preparing for vocations in ministry and lecturing at Union Theological Seminary on Reformed theology and worship as well as Presbyterian polity. Before becoming a minister, Greg used to do things like temp in New York City, design educational software for Microsoft in Seattle, study German history in Berlin, dig ditches and hold stop/go signs in Spokane, clerk at a corporate law firm in San Francisco, and start a Ph.D. program (which he never finished) in Baltimore.

Greg's approach to pastoral ministry is grounded in compelling worship, valuing diverse voices and relationships, the spiritually-transforming experience of serving others while working for social justice, and an openness to embracing the "new thing" that God is always doing. He is dedicated to the biblical vision of an inclusive, Christ-centered community where everyone, of any age or perspective, is welcomed as a beloved child of God and is called to trust God's promises in all aspects of life.

Greg is married to Sarah Touborg-Horn, who is Editor at W.W. Norton & Co. Publishers in New York City. They are parents of high-schooler Will and middle schooler, Maggie. Greg loves to read, teach, travel, ski, re-watch movies, and do anything with his children and his rescue-dogs, Gollie and Percy. He can be reached at  .


Katherine Scott-Kirschner, Associate Pastor for Youth & Families

The Rev. Katherine Scott-Kirschner joined the PCUM church family in March 2018. She is thrilled and honored to be the Associate Pastor of Youth and Young Families at PCUM. Katherine attended Smith College in Northampton, MA and Princeton Theological Seminary in Princeton, NJ.

This is Katherine’s first pastoral call. Before she was ordained to this position, she worked in various capacities in other congregations. She was ordained and installed at PCUM in June 2018. Katherine knew God was leading her into pastoral, congregational ministry at the end of her first year of college. It was not until her final year of seminary that she realized her love of working with youth.

It is her biggest hope that she is able to serve the youth in this congregation by building and sustaining relationships. It is from this stable building block of relationship that other faith-building and faith-exploring opportunities spring forth. She has been known to say, “to make your faith your own, you need to know why it’s important and why you believe it.” It is through the trust from the relationships she builds that deep questions can be discussed and pondered. Then faith is able to grow and mature.

A primary focus for Katherine’s pastoral ministry is teaching the importance of living out the message of Christ’s love in your everyday life by her actions and words. She knew she was called to PCUM when she heard that they also approach the Christian life in this way: church is not just the building, but it is the people who come together to proclaim Christ’s love, God’s mercy, and the Spirit’s presence.

Katherine is married to Donald Kirschner, a Methodist Pastor, and they live in Montville, NJ. She loves to bake, read, take leisurely strolls, practice yoga, and binge watch TV shows on Netflix.
