In 2000 he and his wife, Margie, founded Mary’s Place prayer ministry to create ideal opportunities for people to reorient their lives around prayer and the Word of God. Since that time they have provided week-long, all-expense-paid retreats for pastors and church leaders in locations around the world.

Mary’s Place has expanded its ministry to include life reorientation prayer seminars for church groups around the country, using a guidebook he and his wife developed, called "Choosing Mary's Place."

Because of the impact of this prayer ministry the Free Methodist Church-USA appointed Doug and Margie to serve as co-directors of the National Prayer Ministry in 2014.

He previously served five years as the president of Oakdale Christian High School located in Jackson, Kentucky, a private residential high school for students from around the United States and world.

Prior to going to Oakdale, Newton pastored a Free Methodist congregation in Bowling Green, Kentucky, for thirteen years where his congregation tripled in size. During that time he helped found a city-wide ministry to the poor, worked aggressively for racial reconciliation and integration among the local churches, and received an Outstanding Citizen award from the regional NAACP.
