Greg grew up in Centennial, Colorado as the son of a Lutheran pastor. As he is the great-great-great-grandson of the renowned Rev. Dr. CFW Walther, he felt compelled to continue the family legacy and go into church work. Beginning in 2002, he attended Concordia St. Paul where he acquired a degree in outreach. During his time in Minnesota, he was afforded the opportunity to go on a mission trip to Thailand with the campus mission group, after which he knew that God was calling him into a life on the mission field.
Not knowing what God had in store for him, Greg ended up as the first Lutheran missionary ever sent to a city in Cambodia called Battambang. After surviving for months on junk food and Ramen noodles, God introduced Greg to a local Cambodian girl named Sinuon who would eventually become his bride. Together they have built their home in Cambodia and have three awesome children. Since then he has worked with various ministries in Cambodia in whatever capacity has been needed.
In 2013 Greg and a local ministry partner founded an organization called Crossing Cambodia. The ministry provides primary care, meals, education, and Gospel teaching to street children in Battambang. Greg continues to work in support of this ministry by equipping the local staff to reach out to the children and their families through ongoing fundraising and coordinating volunteers. As a ministry partner with MCN, Greg also helps to develop resources for equipping other missionaries, teams, and short-term volunteers as they seek to share the Gospel in their respective fields.
