Diamond Oaks Worship Center has been a steady presence in Haltom City, Texas, a community tucked inside Tarrant County just north of Fort Worth, for more than fifty years. The church, often shortened to DOWC, belongs to the Church of God (Cleveland, Tennessee) and carries the Pentecostal heartbeat that has shaped the fellowship since its earliest days. Today the church gathers under the pastoral leadership of Chilo and Jessica Grajeda, a husband-and-wife team who serve together as Lead Pastor and Co-Pastor and who have shaped the congregation's bilingual, family-centered identity.
Sunday Mornings at 10:45
Worship at DOWC centers on a single Sunday gathering. The Sunday AM Worship Service begins at 10:45 a.m. in the sanctuary and runs alongside a full Kid's Church program for younger children. Visitors arriving a few minutes early will find greeters from the First Impressions Welcome Team stationed at the doors and at the Welcome Center. They are happy to point out the nursery, the restrooms, the sanctuary, and the fellowship area, and coffee is available before the service begins.
Parking is offered on both the east and west sides of the building. Spots closest to the entrance are kept available for visitors, families with small children, and anyone with mobility restrictions. The church encourages Sunday best and modesty as a way of honoring God and the sacredness of gathered worship, but the welcome itself is offered with grace rather than pressure.
The service itself is rooted in the Bible. Music, prayers, and the pastor's preaching are all grounded in Scripture, and the church holds to the whole Bible as the written Word of God. After the service, newcomers are invited to linger, meet Pastor Chilo, and get to know the people sitting nearby. A dedicated welcome form makes it easy to leave contact information so a staff member can follow up and walk a first-time guest through next steps.
Pastors Chilo and Jessica Grajeda
Chilo Grajeda serves as Lead Pastor and is an ordained Bishop in the Church of God (Cleveland, Tennessee). He holds a Bachelor's degree in Christian Leadership and an MBA, and he preaches and teaches in both English and Spanish. His ministry blends strategic leadership with a clear pulpit presence, and he is often described as a bridge-builder across cultures and generations. He and Jessica, who is an ordained minister with the same denomination, are raising their two sons, Zachariah and Josiah, in the life of the church they lead.
Jessica Grajeda, the Co-Pastor, brings a Bachelor's degree in Education and a shepherd's heart to her work. She directs the Women's Ministries at DOWC and is passionate about integrating community values into the life of the church, encouraging spiritual growth alongside outreach and service. Her writing on her own blog leans into family life, motherhood, and the everyday work of faith.
A Pentecostal Declaration of Faith
DOWC's mission is to perpetuate the full gospel of Jesus Christ, in the Spirit and power of Pentecost, with specific attention to the centrality of God's Word, world evangelization, ministerial development, Christian discipleship, lay ministry, biblical stewardship, church growth, church planting, family enrichment, and servant leadership. That mission lines up with the Church of God's classic Declaration of Faith, which the congregation has adopted as its doctrinal standard.
The Declaration of Faith confesses belief in the verbal inspiration of the Bible, one God eternally existing in three persons, the virgin birth and atoning work of Jesus Christ, repentance, justification by faith, sanctification through the Word and the Holy Ghost, holiness as God's standard of living, the baptism with the Holy Ghost with the initial evidence of speaking in tongues as the Spirit gives utterance, water baptism by immersion, divine healing provided in the atonement, the Lord's Supper and washing of the saints' feet, and the premillennial second coming of Jesus with the bodily resurrection, eternal life for the righteous, and eternal punishment for the wicked.
Alongside doctrine, the church holds to practical commitments that shape everyday life: spiritual example, moral purity, personal integrity, family responsibility, behavioral temperance, modest appearance, and a social obligation to be good citizens, correct injustice, and protect the sanctity of life.
POWER HOUR and ShareLife Groups
On Wednesday nights at 7:00 p.m., the church gathers for POWER HOUR, a small-group hour that runs from 7:00 to 8:00 p.m. POWER HOUR is the weekly rhythm around which much of the discipleship life at DOWC is organized, and it feeds into a broader network called ShareLife Groups.
ShareLife Groups are designed to bring people together in smaller, more personal settings where faith can grow, friendships can flourish, and lives can be transformed. The current groups include a ShareLife Bible Study Group that meets weekly at 7 p.m. to dive into God's Word in a relaxed, discussion-driven setting, and The "W," a community named for its simple commitment: "What is shared in The 'W' stays in The 'W'." The "W" creates a judgment-free space for honest conversation about real-life challenges and the hope of God's Word.
Additional ShareLife Groups are being launched around interests and seasons of life, and members are invited to start their own group by submitting a request through the church.
Children's Ministry
Children's Ministry begins at 10:45 a.m. on Sunday mornings, with check-in opening at 10:30 a.m. for a smooth and safe drop-off. On Wednesday nights at 7:00 p.m., children gather again alongside the youth and adult programming for a separate time of learning and fun. Every leader who serves with children has been fully vetted and background-checked.
Laura Bradley leads the ministry. With more than thirty years of experience in childcare and fifteen years in leadership and administration, plus certifications in Mental Health Coaching and Youth Mental Health Coaching, she oversees a vision to create a secure, joy-filled space where children encounter God's love, build strong foundations of faith, and discover who He created them to be. A fully staffed and safely run nursery is offered during the worship service for the littlest ones.
Youth Ministry
Students in grades six through twelve, ages twelve to eighteen, are welcomed into a vibrant and active youth ministry led by Youth Pastor Elena Longoria. Wednesday nights at 7:00 p.m. are the centerpiece of the week, with a dynamic time of worship, Bible study, and fellowship. Throughout the year the youth ministry adds fun events, outings, and service opportunities that strengthen both faith and friendships. Elena's vision is to see students become passionate followers of Jesus who serve with compassion and make a lasting impact in their schools, families, and communities.
Women's, Men's, Young Adult, and Senior Ministries
Women's Ministries, under Pastor Jessica Grajeda, gathers women of every age and season - teenagers, singles, wives, moms, and grandmothers - through monthly gatherings, Bible studies, discipleship groups, worship nights, conferences, and outreach opportunities. The vision is to empower, equip, and encourage women to live boldly in their God-given purpose, walking in faith, love, and unity.
Men's Ministry provides opportunities for men to come together for worship, community outreach, prayer breakfasts, and shared times like watching a ball game, building friendships while growing in faith.
Young Adults are cared for by Matis and Jadyn Lukalema, who lead with energy and authenticity and a focus on real, everyday connection. They make space for community over coffee, honest conversation about life and faith, and a relaxed rhythm that helps young adults feel at home rather than formal. Matis is pursuing a degree in Biblical Studies, and together they create environments where young adults can ask real questions and discover who Jesus is in the middle of ordinary life.
Seniors are served through the Jesus for Seniors Ministry, coordinated by Sonny and Cecilia Deverney. Sonny is a retired veteran who served in both the United States Air Force and the Marines, with avionics communications work on the SR-71 and TR-1 aircraft. Cecilia is a master crocheter who brings creativity and warmth to every gathering; she is also Pastor Chilo's mother. Together they create a welcoming space where seniors, whether new to church or lifelong members, feel seen, valued, and deeply loved.
Worship Ministry
Worship at DOWC is led by Pastor Alyssa Mackey alongside her husband Pastor Reggie Mackey, who together serve as Assistant Pastors and Worship Co-Pastors. Alyssa oversees a team committed to ushering the congregation into moments of praise and surrender, with a blend of contemporary and gospel styles that the ministry describes as a meeting of freedom, joy, and reverence. The core values of the worship team are presence over performance, excellence with humility, unity in diversity, and growth through worship.
Vocalists, musicians, sound techs, and anyone with a heart for worship and creativity are invited to explore opportunities to serve on the team.
Discipleship Ministry
The Discipleship Ministry frames its work with the phrase "Growing in Christ, Together." It is built around spiritual growth, life-on-life mentorship, community connection, leadership development, and missional living. Practical pathways include Foundations of Faith classes, beginner to advanced discipleship cohorts, one-on-one mentoring, men's and women's discipleship gatherings, leadership development courses, and youth and young adult tracks. The aim is not a single program but a lifelong journey of becoming spiritually mature followers of Christ who live out the Great Commission in their homes, workplaces, and communities.
Local Outreach and the Food Pantry
Beyond Sunday and Wednesday gatherings, DOWC runs ministries that extend into the wider Haltom City and Tarrant County community. A Food Pantry is one of the standing ministries listed alongside Bible study classes and weekly prayer meetings, and outreach is woven into the mission of giving, with giving directed in part toward outreach and local missions.
Giving
Giving is described as one of the ways the congregation worships. Four options are offered: in person during any service, online through the church's secure giving system, by text from a mobile phone, or by mailing a gift directly to the church. One-time gifts and recurring withdrawals can both be set up, and contributions can be directed to the church's general fund, tithes, or a specific fund or department.
Pastors' Blogs
Both pastors write regularly. Pastor Chilo's blog covers encouragement and biblical insight with titles such as "Listen Carefully," "All Ups, No Downs," "On the Verge of Once More," "What Does the World See?," "The Waiting Game," and "Searching the Scriptures." Pastor Jessica's blog, with a more personal and family-centered voice, includes posts such as "Snapper Chappers and the God Who Meets Us in Every Season," "The Fine Line Between Waiting on the Lord and Stepping Out in Faith," and "Rubik's Cube - Then and Now." A Prayer Wall is also available for anyone who wants to share a request and let others pray.
