Dr. Kevin Callahan


Kevin Callahan, with 16 years at IPM, holds the role of President. Collaborating closely with executive staff and department heads, I guide administrative decisions, steering IPM’s course in alignment with our Board of Directors. My responsibilities extend to conducting future-planning meetings, vital for charting our organization’s trajectory, and engaging with key contributors.

My academic journey, culminating in a BA and MA in Bible from BJU, along with a DD from SIBBC&S, laid the foundation for my dedication to missions. Early on, I engaged with Mission Team West, working among Mormons in the western US during my time at BJU. As a pastor, I resonated deeply with IPM’s missions philosophy, supporting its missionaries and eventually serving on the Board of Directors, eventually becoming its chairman. Stepping into the role of IPM’s President was a calling affirmed by the Lord. I attribute our success to prayer and reliance on God’s strength, finding perfection in our weaknesses. All glory rightfully belongs to Him for the work accomplished at IPM.

Matt Barfield

VP of Field Ministries

Matthew Barfield is IPM’s Vice President of Field ministries, a role he’s held for over a decade.  He and his wife, Chrysta, have been with IPM for 21 years, first serving in the Middle East as part of a church planting team. After planting a church and starting a Bible school with an Arabic church planter in Jordan, Matthew contracted a parasitic illness that led to big changes in their lives and ministry. 
Once the Lord returned him to health, Matt began traveling as IPM’s missionary evangelist. He preached for evangelistic and revival meetings around the world, something he enjoys doing to this day.
In 2016, Matt, Chrysta, and their eight children began the Next Door Nations program, IPM’s stateside ministry to foreign nationals. That work has grown, and several churches across the country are starting their own cross-cultural ministries right here in the USA. To learn more, check out Matt’s book, Next Door Nations, on
