Brian & Christie Holben

Brian: Operations Director and austell campus director Christie: Austell Campus team member

Brian and Christie met in middle school, and have now been married for 12 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, two young men from their neighborhood, 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,

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!

Ivaylo Yordanov

Toastmasters Coach

Ivaylo is fascinated by why people do the things they do and what creates lasting change in individuals and organizations. As a professional coach (certified by the Robbins-Madanes Center for Strategic Intervention), he aims to help people see their problems and challenges from a different perspective.

He says, “My job is to have meaningful conversations that make a difference. I believe change can happen so quickly if you help someone see the world (their world) differently. One distinction or insight can sometimes turn an impossible situation into one full of hope and possibility. That moment, when people light up, makes everything I do worth it!”

Ivaylo uses his coaching skills at Chick-fil-A as a Director of Development where he works with team members to grow their leadership skills and achieve their personal and professional goals. He teaches workshops, speaks at schools and is committed to helping people become more through work. He believes work can be a place people realize their true potential.

When he’s not working, you can find him playing the guitar or reading. Ivaylo’s from Sofia, Bulgaria. He moved to the United States with his family in 2002.
