The Team

ROI Ministry delivers confidence in your giving decisions - impact for your giving dollars.

Tim Barker

After traveling around the world, God gave Tim a heart for helping people, Tim discovered research showing that only less than 1% of worldwide Christian giving is used to help the poorest, lost people. He also discovered that this is where the greatest lasting impact per dollar was being made. Tim became passionate about sharing this information and thus began ROI Ministry. As the founder of ROI, he represents the ministry to individuals and organizations, provides leadership to the board, and continues to carry out the mission and vision of ROI Ministry. He spends the rest of his time working as a Decommissioning Program Director for AECOM, one of the largest engineering construction firms in the world.

David Mimms

David has a passion for bringing ministries and people together to serve God. At the root of this passion is David’s heart for people in the world who are without the knowledge of Christ. When Tim approached him with the idea of ROI Ministry, David knew it was a ministry that would greatly impact many people around the world. David’s focus as co-founder of ROI Ministry includes networking, building relationships and providing leadership. David also acts as Chairman of Mimms Enterprises, a fourth generation, family-owned commercial real estate developer based in Roswell, Georgia.

Chip Brackley

After years of advising others about financial giving, Chip was always asked the same question by his clients. Will my money be spent wisely? Chip believes that ROI Ministry is key helping people answer that question by giving donors confidence that their money will have a significant impact. Chip is a servant leader and is willing take on any task asked of him. In addition to his role on ROI Ministry’s board, Chip spends his time as Managing Director of the wealth management practice, Lakeview Capital Partners.

Randy Walton

Randy joined ROI Ministry’s board because he is convinced that there is a growing spirit of generosity in the Christian community that desires to fulfill God’s commission, but lacks the confidence to do so. Randy believes ROI Ministry exists to provide confidence in giving and that doing so will mobilize great wealth for God’s glory. As a founder of The Walton Group and member of multiple boards, Randy brings deep wisdom, strategic thinking and organizational skills to ROI Ministry.
