Biography

Wayne Gray serves as Chief Executive Officer of Adult & Teen Challenge of Oklahoma, bringing more than 40 years of ministry experience within the Adult & Teen Challenge movement both in Oklahoma and nationally. Throughout his career, Wayne has faithfully served in a wide range of roles including intake coordinator, vocational director, pastoral counselor and mentor, executive director, state director, COO, and CEO, giving him a deep understanding of every level of the organization. Wayne’s calling into ministry began when Teen Challenge workers shared the gospel with him and invited him to church and their inner-city outreach center. This encounter ignited a lifelong passion for helping individuals find freedom from addiction and life-controlling problems through Christ-centered recovery. He also served as a pastor for three years, further strengthening his heart for discipleship and spiritual leadership. One of Wayne’s greatest joys is witnessing students enter the program broken and hopeless, then leave transformed—often returning as staff to offer hope to others. His vision includes expanding Adult & Teen Challenge into Kansas and growing the Freedom Challenge prison ministry throughout Oklahoma. Wayne’s greatest hope is that every student completes the program and experiences lasting freedom and transformation through Jesus Christ.

Biography

I have had the privilege of serving with Adult & Teen Challenge for over 28 years—four years in Arkansas and, since 2002, in Oklahoma. My journey with ATC began after being impacted through visits to the Dallas and Midland, Texas centers. I felt a deep calling, one that grew stronger as I got older, eventually leading me to serve full-time. Over the years, I’ve taken on many roles including teacher, counselor, intake coordinator, court liaison, assistant director, and program director. I’ve helped build GED programs, trained staff, and led audit preparations. I also have experience in outreach, recovery ministry, hospital work, and pastoring. As a former student at the Florida ATC, I experienced God’s transformative power firsthand. I helped in the office and with the GED program, and it deepened my calling. I love meeting people, learning new skills, and finding strength through challenges. My hope for every student is that they grow in God, prepare for real life, and know they are loved. My vision is to expand outreach, especially in prisons, and to equip others to carry the torch. I believe in overcoming hardships—and I don’t give up.

Rev. Kathy Love

Freedom House Adult & Teen Challenge
Executive Director

Biography

Kathy has served at Freedom House for over 16 years in a variety of roles, including Church Service Coordinator, Direct Care Supervisor, Program Manager, and, since 2020, Executive Director. Although she was never a student in the program, she grew up in a dysfunctional family—an experience that instilled in her a deep sense of compassion and empathy for others. Prior to joining Freedom House, Kathy completed Bible school and received both her Ministerial License and Ordination. She co-pastored a church for 12 years, served as a chaplain in a county jail, and has a background in special education. She also worked extensively with the Department of Human Services and the University of Oklahoma, training current and prospective foster and adoptive parents. Over a span of ten years, Kathy has fostered 39 children. She is the adoptive mother of eight and the proud grandmother of 11. Her favorite part of working with Adult & Teen Challenge is witnessing women develop a personal relationship with Jesus and experience freedom from addiction and other life-controlling issues. “I love seeing them become successful women and healthy mothers. It’s amazing to watch them reunite with their children and raise them to know Christ. One of the unique aspects of our center is that we accept pregnant women. They can bring their babies home from the hospital and live with them on-site. We also collaborate with families and DHS to support moms working toward reunification. While we don’t initially bring children in with their mothers, we believe it’s important for the women to first focus on their own healing.” In addition to her passion for ministering to women, moms, and children, God has also given Kathy a heart for restoration students—those who have completed a program but continue to struggle. Her hope for every woman entering Freedom House is that she would develop a deep, intimate relationship with the Lord, receive the deliverance she needs, and never return to the lifestyle that once held her captive.

Biography

My journey with ATC began in 2001 when I walked through the doors strung out on heroin and crack cocaine after trying five other secular programs that didn’t work. But everything changed when I was introduced to Jesus Christ. Just three months into the program, I knew God was calling me to stay and help other men find the same freedom I had found. Since then, I’ve served in nearly every role—teacher, counselor, program manager, intake coordinator, business manager, assistant director, and now Executive Director. I’m passionate about working with men and their families, helping them break free from addiction and codependency, and guiding them into new lives rooted in Christ. My vision is to grow the men’s center to a 40-bed facility, open a Super Thrift, and eventually launch both men’s and women’s programs in Wichita and Kansas City. I believe deeply in the power of transformation and vocational training, and I want every person who comes through our doors to experience total freedom in Christ, restoration with their families, and a new life as a bold witness for the gospel. Outside of ministry, I’m a husband and dad who loves his family dearly, I’m someone who truly loves Jesus and longs to see lives changed.

Executive Director Green Country Adult & Teen Challenge of Oklahoma

Biography

As of February 2020, I have been blessed to serve as the Executive Director of Green Country Adult & Teen Challenge. For many years, I was hopelessly bound by an addiction to heroin, which led me to places I swore I would never go. In 2009, after losing everything that mattered to me, I found myself facing several years in prison. But God, in His mercy, strategically placed someone in my life who had graduated from a program called Teen Challenge. They said, “Stephanie, the only way you will ever find the peace you’re so desperately searching for is if you go to this program and surrender your life to Jesus Christ.” I entered Adult & Teen Challenge in July 2009, and from the moment I walked through the door, God met me and began radically transforming my life. Six months into the program, He gave me a vision one night—a vision of running an adult women’s center. That night, I knew I was being called into full-time ministry to help other women who were walking through the same darkness I had once experienced. My favorite part of this ministry is watching the Lord take broken women and turn them into trophies of grace. I cherish the one-on-one moments where I get to see lives changed by a single encounter with God. My heart’s desire is for Green Country Adult & Teen Challenge to grow and become a true safe haven for women in need. Because we are a smaller center, we have the opportunity to spend more personal time with each woman who comes through our doors. My prayer is that every woman who walks in would immediately feel the love of Jesus Christ and experience total freedom from the bondage that once held them captive—just like I did when I came to Adult & Teen Challenge.

Biography

I’ve served with Adult & Teen Challenge for 14 years, taking on nearly every role from teacher and fundraiser to program director and executive director. My calling to this ministry began during a church presentation on Teen Challenge, where I felt a clear conviction that Oklahoma needed a women’s center. I trained in Dallas and Houston, and during a pause in progress due to the state director’s illness, I launched a re-entry home for women coming out of prison. Outside of ATC, I’ve worked as a chaplain with the Assemblies of God and founded Living in Freedom Today, a 501(c)(3) recovery program now known as Freedom Challenge Mabel Bassett, serving women inside Oklahoma’s largest prison. I’m a determined person, more comfortable behind the scenes than in social settings, but passionate about ministry and seeing lives transformed.
