The following people make up the Board of Directors of the DTI ministry.

Art & Toni Barkley became Christians in 1961 in Salt Lake City, Utah. In 1964 they entered the New Tribes Mission "Boot Camp" training, then in 1970 they, along with their two sons, ages five & seven, traveled to Bolivia, South America to serve as missionaries to jungle tribes. They continued serving with New Tribes Mission until 1991, when the Lord changed the direction of their ministry. He arranged for Art to spend the next 7-1/2 years as an associate pastor at Reno Christian Fellowship (RCF) in Reno, Nevada. During that period, God took Art through a learning experience in the area of discipleship that changed his whole perspective. In March of 1999, Art resigned his position at RCF, founded the Discipler Training International (DTI) ministry, and authored the discipleship manual titled “A Tool for Personal Discipleship”. Art, along with his wife, Toni, continues to promote discipleship concepts and the training of disciplers in Reno and worldwide through the Internet. Art & Toni continue to live in Reno, where Toni also disciples and counsels women.

Adam Barkley grew up in Bolivia, So. America, where his parents (Art and Toni) served with New Tribes Mission (NTM). Adam graduated from the NTM school (Tambo) in 1981, and then from the NTM Bible Institute in Waukesha, WI. Adam served as pastor at the First Baptist Church in Gardnerville, Nevada for eight years and is presently an itinerate pastor at TRE Baptist church, Wellington NV. He is also presently a full time Hospice Chaplain working at Infinity Hospice Care in Reno. Adam has a passion for seeing believers grow to a mature fruitful relationship with the Lord. He pursues this in both his ministry as a pastor and in ministries with DTI.

Leo Castro's Christian journey started in 1984 in San Jose, CA. In 1985 Leo met Alvina who he married in 1989. Leo graduated from Trinity Ministries in San Jose, CA in 1992 and received his ordination as a minister at the same time. Leo has served as an Elder, Chaplain, Youth Pastor and Associate Pastor in San Jose. After moving to Reno, NV Leo served as an Associate Pastor at Pathway Christian Church and also served as the Senior Pastor at Iglesia Cristiana Summit from 2005 to July of 2013. Today, Leo is the Senior Pastor and founder of Iglesia Eternidad (Eternity Church) in South Reno. Iglesia Eternidad's mission is to glorify God by equipping every believer to fulfill the Great Commission.

Leo's involvement with DTI began in 2008 with a request for information from the DTI web site. After meeting with Frank Meitz, they decided to commence the TTT (Train The Trainers) initiative at Iglesia Summit and in July 2013, it was decided that DTI needed to be a vital part of the new DNA at Iglesia Eternidad. Today, the church has a discipleship gathering every Sunday morning led by Art & Toni Barkley. In his spare time, Leo and Alvina love kayaking, biking, reading, and being with their two boys and dog.

Jerry Cole has been in ministry for more than 35 years. As a pastor, Jerry used the DTI materials and the philosophy of personal discipleship in growing the church. He sees personal discipleship or "spiritual parenting" as the key to a healthy church. Jerry believes that every sermon, Bible study or Biblical presentation he has ever prepared has one or more of the basic elements of the DTI material. So much so, Jerry has recently written a book titled, "The Course". One of its themes centers on discipleship. Jerry says, "My mission in life is to simply tell people about Jesus." Jesus' command is to "Make Disciples".

Evan Gannon accepted Christ as Savior on January 21, 1995, and began attending Reno Christian Fellowship in Reno, Nevada. Evan was introduced to Art Barkley in 1997 and was personally discipled by Art. Evan made a Lordship decision after learning from Art about Christ's desire to be more than Savior, but also Lord. From that time forward, Evan actively attended Art's Sunday morning class, and his desire to personally disciple others has continued to grow, resulting in the discipling of Church leaders, small groups and individuals.

Evan moved from Reno to Dayton, Nevada in 2010. He is currently training Disciplers in Dayton, working with two couples one on one and leading Bible study classes on the topics of Revealing the Mysteries of Heaven, The Abiding Life, God and Country and Understanding the Bible. He also serves our Lord as Advisory Board Secretary for DTI, as Administrator of Dayton Valley Community Church and member of the Dayton Valley Ministerial Alliance.

John Hill's first church experience was in the Presbyterian Church in Casper Wyoming. In 1956 he went to The College of Idaho where he met the love of his life TJ. His key work and church experience has been an up and down adventure with a great opportunity to work full time in the Boy Scouts of America, building up the young men of the nation to live a life based on moral values. He and TJ moved to Portland to serve with the Columbia Pacific Council of the Boy Scouts. John was ordained as an elder in the Kenilworth Presbyterian Church in Portland, Oregon in 1964. In 1968 they moved to The Snake River Area Council in Twin Falls, Idaho where he served as the Director of Finance until 1971.

When John looks back on his life it is evident that God was at work shaping him into what He wanted not what John was trying to achieve. In 1968 John and TJ moved to Carson City, Nevada, and got involved with a men's Bible study. They were then led to Covenant Presbyterian Church in Reno where they recently led a class on The Five love Languages. Four years ago at a weekend Men's Retreat at Lake Tahoe, John and the men of Covenant invited DTI to present their "Spiritual Parenting" model of discipleship to the group. Following that weekend the men, including the pastor, decided to meet weekly studying "The Tool" with Evan Gannon from DTI who faithfully arrived at Covenant at 6:00 AM every Monday for 18 months. This has forever changed the way John looks at relationships. It is a heart changing process that has far reaching effects on a greater scale than just the ones that go through it.

Frank and Jeannette Meitz decided when they married in 1995 that their relationship would include God. As a preacher's kid, Jeannette had accepted the Lord early in her life. Frank was raised Catholic, yet did not understand salvation and a personal relationship with the Lord until they spent the first four years of their marriage participating in, and then leading, a Bible Study. Their experiences also included several short-term mission trips. In 2004 the Lord led Frank and Jeannette to begin attending Reno Christian Fellowship in Reno, Nevada. A few months later they started attending Art and Toni Barkley's Sunday Discipler Training class. The Holy Spirit gave them ideas of how to assist the DTI ministry, such as developing a user-friendly CD-ROM (that people worldwide request from the DTI Internet website). In 2006 they attended the "Perspectives" Missions class, which highlighted for them the importance of "spiritual parenting" new believers. After participating in the first DTI "Train The Trainers" workshop in Ensenada, Mexico, Frank clearly heard the Lord telling him to join Art as a full-time volunteer. He resigned from his 24-year position as a Technology Trainer, and on January 1, 2007, began serving as Director of Operations and spearheading the "Train The Trainers" branch of the DTI ministry.
