The roi ministry podcast

After meeting Tim Barker and learning his story and vision for ROI Ministry, I felt called to join the board in 2022.  I continue to be blown away by the impact this ministry and our partners are having around the globe.

My wife, Denise, and I have been married for 26 years and have three awesome kids.  Ethan is an engineering student at Ole Miss, while Reagan and Addi are student athletes in middle and high school.  Denise and I have a passion for the ‘Now Generation’ and have been serving as leaders for middle and high school students for over eight years, including leading students on international mission trips and local efforts in the Atlanta area.

I was baptized at 16 and spent the next couple decades chasing religion but lacked a personal relationship with Jesus.  In recent years I began to understand that Jesus died to secure my purpose here and now and that the Kingdom of Heaven is alive and all around me.  With ROI Ministry and the ministry partners, I see God moving and doing incredible things. It is a privilege that I get to step in and be part of this mission. LinkedIn

From a desire to see God’s kingdom expanded all across the world, I began serving as a Board Member of ROI Ministry in 2011. The opportunity to learn and see where God is moving, along with how God’s spirit is stirring the hearts of people in other parts of the world, has been the primary reason I continue to serve ROI Ministry and the ministries we endorse.

Currently, my wife and I are empty nesters. With two sons in college, and a real estate development business which leaves me plenty of margin for other pursuits, my wife and I are enjoying asking The Father what He has to say to us, and what He has for us to move in now.

Through the prayers and efforts of the ministries which ROI Ministry endorses, it is my hope that more than 1 Billion people receive Jesus Christ as their Savior and Lord during 2015 – 2030. More important than the numbers of people proclaiming Jesus as Lord is the testimony of a person simply sharing “Jesus came into my heart, and His power changes me. Now I live to please my Lord, Jesus”. Linkedin
