Our Team

Tara-Leigh Cobble

D-Group Founder & CEO

Her earliest memory is learning John 3:16 from her mom, shortly before her brother led her to Christ. Despite an early introduction to Christianity, she wasted years coasting on the second-hand information she learned from others. In 2008, through the gentle encouragement of a friend, she read all the way through the Bible for the first time. That changed everything. "I wanted and needed people alongside me in my pursuit of God -- people to hold me accountable for scripture memory and Bible reading and all the things that were bringing me so much newfound joy!" Out of that need, she started D-Group with a handful of strangers in a living room in 2009. She lives in Dallas, TX, where she has no pets or children - or anything else that might die if she forgets to feed it.

RACHEL
MANTOOTH

Chief of
Staff

LINDSAY
RUHTER

Administrative
Assistant

As the daughter of a Minister of Music, Rachel grew up being at the church "every time the doors were open." She became a Christian at the age of six but it wasn't until joining D-Group that she was truly challenged with the question, "Is what I believe deeply rooted in scripture or is it just what was taught to me as a child?" Through processing that question, God strengthened the truth of her faith and gave her a burning desire to know Him and His Word more. Rachel lives with her husband, Chase, and their two sons in Simpsonville, SC. They are members of Brookwood Church in Simpsonville.

Lindsay grew up in a loving, Christian household and came to know Jesus as her Savior at 7 years old. In recent years, she has pursued a much deeper understanding of Scripture and her relationship with God, and as a result, she’s zealous about inviting others to join her in D-Group and The Bible Recap. She loves getting up early to spend time learning with her online D-Group! She enjoys doing anything creative and RV camping with her family. Lindsay lives with her husband, Grant, and their two kids in Fort Worth, TX.

MEG
MITCHELL

Leader Care
Director

LAUREN
MULFORD

Senior Management
Theology + Content Director

As a child, Meg taught Bible stories in front of her dolls, stuffed animals, and any neighbor she could convince to listen. Over time, her zeal for God morphed into merely serving Him, which led her to a season of spiritual burnout. In His kindness, the Lord awakened her heart with reminders of who He truly is. She genuinely desires to spend her days “testifying to the gospel of the grace of God” (Acts 20:24). She lives in Dallas, TX, where she enjoys a spontaneous game night and serves at City Church International.

Lauren came to trust Christ with her salvation at the age of seven. She trained to be a professional ballet dancer with Ballet Magnificat and served as a missionary with them for three years traveling across the USA. She later went on to receive her bachelor’s degree in biology from the University of Texas at Arlington where she met her husband at a Bible study. D-Group catapulted her to “love God and love people” more than she had ever previously while maintaining doctrinal integrity. She is currently studying for her M. Div. at Grand Rapids Theological Seminary as a Pirsig Fellow.

WARWICK
FULLER

Men's
Director

LAURA "LB"
BUCHELT

Senior
Management

Warwick’s life testifies to God’s loving pursuit of him. He went to college and seminary in PA, where he developed discipleship programs for individuals, groups, and families. He is an ordained minister in the ACNA, serving as a US Army Chaplain. Framing his life around Galatians 2:20, he wants to see everyone rooted in Scripture, surrounded by community, and able to articulate what they believe. He has a deep love for God’s Word and is happy to be a part of the D-Group movement! He is married with 4 kids and serves currently as the Chief of Research and Development at the Chief of Chaplain's Initiatives Group at Ft Hamilton, NY. He and his family attend Emmanuel Anglican Church in NYC.

As a pastor’s kid, LB vowed she’d never go into full time ministry. She loved Jesus, but ministry required a faith she wasn’t sure she possessed. When God softened her heart and called her to a life of ministry, she knew it could only be accomplished by His strength, not her own. Her heart for Scripture and discipleship has continued to deepen since she began vocational ministry in 2009. She cherished the truth of Philippians 2:13: It is God who works in her, both to will and to work for His good pleasure. She lives in Dallas, TX, where she is on staff with D-Group, The Bible Recap, Israelux and The God Shot.

EVALINE
ASMAH

Theology &
Content Assistant

Evaline was a quintessential Bible-Belt church kid who knew God loved her and Christ died for her, but faith was often reduced to trying to follow “His rules''. After high school the Lord gave her a fresh understanding of both the weight of sin and the glory of grace—that changed her life and produced a hunger to know Him more deeply and learn to really walk with Him. Through that time, God taught her about His love and what it meant to be a fisher of men. She hopes to spend the rest of her life growing in those things! Evaline currently calls Dallas, TX, home.
