MB Foundation announces the addition of two new team members: Eric Buller and Darin Ediger.
Eric Buller joined MB Foundation as chief operations officer in September 2025, bringing over 30 years of cross-sector leadership in nonprofit operations, healthcare, missions and manufacturing. Most recently, he served as CEO of ELWA Hospital in Liberia, Africa. Buller, his wife Pam and his children will soon be relocating to Hillsboro, Kansas, and are already active in Parkview MB Church and the community.
“After 14 years of church planting in Liberia, I see this role as a continuation of my calling—helping ministries thrive,” Buller says. “As COO, I’m focused on strengthening systems and communication so we can serve our clients even better.”
In November, Darin Ediger joined the team as planned giving advisor. He brings 30 years of experience in the financial services industry, having worked with Charles Schwab and Fidelity Investments in Denver. Ediger also served in a nonprofit ministry, supporting families overcoming setbacks. He and his wife, Tammy, have also relocated to Hillsboro.
“I’m grateful to serve with MB Foundation and to partner with individuals and families to steward God’s resources for his glory and eternal purpose,” Ediger says. “I look forward to building meaningful relationships and supporting our constituents as they pursue generous giving that reflects their faith.”
“We’re thrilled to welcome Eric and Darin to our team,” says Jon Wiebe, MB Foundation president and CEO. “Their expertise and passion for ministry will strengthen our organization and enhance our ability to serve our constituents. We praise the Lord for his provision and thank our constituents who have prayed for these openings and encouraged folks to join our team.”
