Brian & Christie Holben
Brian: Operations Director and ATlanta Campus director Christie: team member
Brian and Christie met in middle school, and have now been married for 15 years! Over the years, their lives and vocations have taken them from working overseas in East Asia, to community outreach, to pastoral ministry with a local church, to serving international students in Atlanta, and now to Four Corners Group.
They have lived in their neighborhood in downtown Atlanta (shoutout to the SWATS!) for almost 10 years, and this has opened their eyes to both the beauty and the struggles of those who are often marginalized in our society. Over the years they have become increasingly burdened for social justice, particularly as they’ve witnessed undeniable patterns, systemic issues, and common denominators across lower-income Black and brown communities regardless of zip codes. As they’ve “become family” and walked with many of their neighbors through the trauma of incarceration (as well as things like unjust evictions, shootings, discrimmination, and the effects of poverty), they have been filled with a passion to push back against the forces of oppression in our society. They have had the privilege to mentor several young men and women from their neighborhood, as well as to offer their home as a place of light and refuge to many. They firmly believe that each person, no matter their background, record, rap sheet, education, income, or race has God-given worth, dignity, and assets to offer our world.
Brian and Christie’s family – their “crew” as they call it – is a tapestry of individuals woven together in unlikely but beautiful ways. Together in their home they currently have their two young sons, Goddaughter, and their spiritual brother from the country of Nepal. In their free time they love having block parties and playing Spades with their neighbors, exploring new places, cooking/eating food from around the world, and drinking good coffee.

Colby Hall
Spanish Family liaison,
Mentor
Colby Hall is passionate about developing relationships and learning from those who are different from him. He believes that Jesus calls his followers to serve and love others, seek justice for the oppressed, and have compassion for those who are hurting, and FCG has given him and many others a way to follow that calling.
Colby was born in Conyers, GA and has lived in Loganville, GA, a small town east of Atlanta, for almost his whole life. His regular trips visiting relatives in the Northeast US ignited his interest for travel and experiencing different cultures and languages. Beginning in his high school years, that interest inspired him both to start studying Spanish and to volunteer with Haven of Hope International’s Refugio de Esperanza Orphanage in Santa Cruz de la Sierra, Bolivia, which he regularly visits on mission trips to serve and love their at-promise youth. After graduating from Georgia State University in 2019 with a B.A. in Applied Linguistics and a minor in Spanish, Colby is thankful for the chance that FCG gives him to use his language skills and be a regular, encouraging presence in the lives of at-promise students.
Colby brings over 6 years of serving at-promise/orphaned youth, Spanish language skills, and general communication and intercultural skills to his role. As a Mentor, he maintains regular communication with students and their families about their progress, celebrating in the students’ highlight moments and encouraging them at their low points.
One of Colby’s primary additional interests is music. He writes, produces, arranges, and plays various musical instruments for his band, LOOKiT, and he also produces music for other artists. He is an avid New England sports fan due to his New England roots; lastly, he still loves to travel, especially to places where he can practice his Spanish!
Katia Bowers
Marietta Campus Director
As a first-generation Haitian American, originally from Fort Lauderdale, FL, and a Georgia resident for over 15 years, my journey has been shaped by resilience and a deep commitment to service. My story, filled with its own challenges, fuels my desire to be the healthy and impactful adult I wish I had during my formative years. This personal motivation drives my 17 years of experience working with youth, particularly underprivileged students, in various capacities. My most recent role as YoungLives Coordinator in Marietta, GA, allowed me to directly support teen moms by providing essential life skills classes, resources, support groups, mentoring and enriching programs and camps.
At Four Corners Group, I am thrilled to leverage this experience to create impactful initiatives that resonate with young people. I am passionate about empowering the next generation and fostering meaningful community connections. My dedication to mentorship and collaboration aligns seamlessly with Four Corners Group’s mission to uplift and inspire. I believe in building supportive environments where youth can thrive, providing them with the tools and opportunities they need to reach their full potential.
Beyond my professional life, I cherish time spent with my wonderful husband, Pastor Michael Bowers, and our four children, Michael, Eli, Ryleigh, and Kyla. When I’m not working, you can find me indulging in my hobbies, which include singing, reading, and traveling. These activities not only bring me joy but also provide valuable perspectives that enrich my work and my understanding of the world.

Dexter Miller
Austell Campus Director
Dexter Miller is the Austell Campus Director at Four Corners Group, where he works to empower youth and help them unlock their full potential. Originally from Boston, MA, Dexter grew up witnessing many of his peers struggle to reach their goals—not because of a lack of talent or ambition, but because they lacked access to necessary resources and support. This realization would fuel a lifelong dedication to creating opportunities for young people facing similar challenges.
His passion for youth development deepened through roles working in a county jail and a homeless youth shelter. In both settings, Dexter saw firsthand how trauma, instability, and systemic barriers could really derail young lives but he also how consistent guidance and care can change everything.
In his spare time, Dexter enjoys practicing yoga, hiking, going for runs, and getting lost in a good book.
