This is the team that will be devoted to your project. We work well together because our backgrounds are diverse. We are well-rounded, creative thinkers and as a team, our ideas are even better. Most importantly, we will spend time getting to know you so the end result looks good and makes sense.

Kriston Sellier


In her role as CEO of id8, it is Kriston Sellier’s responsibility to cultivate the company culture she has envisioned since she opened the agency’s doors in 2000—one that nurtures new and innovative thinking, a relaxed approach to communicating with clients, and an understanding of the critical role design thinking plays in every business strategy.

Julie Cofer

Art Director

Julie Cofer has been bringing mentoring and leadership to id8 since 2004—and a lot of butt kickin’ energy—to her role as Art Director. She is responsible for executing and managing multiple brand initiatives across both digital and print platforms. With more than 15 years of design experience, Julie is a highly creative thinker who provides unique solutions and strategies for id8’s clients, such as Atlantic Realty Partners, Greater Women’s Business Council, Inland Market (a division of Inland Seafood), Boys & Girls Clubs of Metro Atlanta and Andersonville National Historic Park.

Prior to joining id8, Julie worked with major clients, including the Mall of Stonecrest, Harley-Davidson of Atlanta, Pfizer Pharmaceuticals, AstraZeneca, Marcus Autism Center and Federated Department Stores.

Julie has won numerous design awards from Graphic Design, USA (GDUSA) and American Graphic Design & Advertising (AGDA Award) and was featured in Graphis’ New Talent Annual in 2001. She has a Bachelor of Fine Arts in Communication Design from the Atlanta College of Art.

Part of a “dying breed” of native Atlantans, Julie is married with two young daughters. And even though she lives in the “sticks” and loves her daily view of horse farms and cow pastures, she still goes back to her city girl roots for date nights and socializing with friends.

Ashley George

Production Artist

As Production Artist, Ashley George will tell you she’s never been a “typical right-brain designer.” She loves the analytical and methodical aspects of the creative world, so her role as a Production Artist is the perfect fit. She is responsible for the production and pre-press stages of every id8 project. She uniformly creates the project management schedule for each approved job, accounting for all the details so it is completed successfully. This requires working closely with each designer, ensuring consistency in the design and that each file conforms to industry standards.

Ashley has a Graphic Communications degree from Kennesaw State University, and although she has a background in production and graphic design, both her heart and her brain are in production, where she loves being able to tackle both the technical and the creative aspects of projects.

Before joining id8, Ashley produced creative work for local community magazines, Glock ID, Mizuno, Must! Charities, Global Lending Services, and General Mills through national retailers, including Walmart, Publix, Target, and Kroger.

Ashley is a North Georgia native living in the Woodstock area, where she dabbles in self-taught hand-lettering and reads action-adventure fiction. She builds furniture with her husband, Kevin, and watches scripted TV with her dog, Leela, and ferret, Newton. Ashley and Kevin welcomed their first child in December, Atlas Watson, a sweet little girl with lots of hair.

JoAnne Sellors


JoAnne Sellors manages the books for id8, keeping things running smoothly on the accounting side of the business. She will tell you two things: “I love working at id8; it’s a wonderful, cheerful atmosphere with great people,” and “I know that I’m strange, but I enjoy working with numbers.” We’re glad about both.

JoAnne has been working in the accounting field since 1981—taking some time off to raise her five children. Before joining id8, she earned a Bachelor of Science in Accounting from Towson State University in Towson, Maryland and held accounting positions with Manganaro Corporation, American Trading and Production Company, and The Mahone Group.

After moving from her home state of Maryland in 2002, JoAnne and her family relocated to Atlanta for Matt’s job and also opened their own coffee shop in id8’s home town of Marietta. She is happy to report that The Daily Grind has been a community favorite spot for 8 years.

When she’s not snuggling with her new grandson (her first grandchild!), JoAnne enjoys sewing, baking, crocheting, knitting, reading, and spending time with family and friends.

Emily Stiles

Agency Assistant

Emily Stiles’ job is hard to describe with a simple title. She answers the phone, greets clients and other guests, keeps track of the team calendar, coordinates projects, manages id8’s social media, plans and executes events both for id8 and for clients, and does some writing and proofing on projects to boot. In short—she keeps the office humming. Her attention to detail, organizational skills, and cheerful disposition makes her perfect for the position.
So how does she do it? “I begin each day ready to meet the needs of my coworkers and our clients, and I leave feeling inspired, challenged, and proud of the team I work with—and I know what I do contributes to the bigger picture of creating a winning experience for our clients and our business.”
Emily earned a B.A. in Mass Communication with a concentration in Public Relations from Georgia College & State University. After graduating, she moved to Ireland and worked there for nearly two years. Her experience also includes partnering with non-profits, including international Operation Mobilization (OM) teams and the Greensboro Main Street Program.

Emily is a native of Marietta and volunteers at her church located near the Square. She supports OM Ireland, Cru, and the Homeless Pets Foundation. When she’s not at the office, Emily enjoys hanging out with her husband, Michael, and their puppy, Murphy, getting her hands dirty in her veggie garden, and exploring the trails of Kennesaw Mountain.

Madge Caldwell

Business Consultant

Madge Caldwell of Caldwell & Pate has been providing business consulting and coaching in business management to id8 since 2013. She has been coaching business owners and professionals in industries from manufacturing to retail to financial services, including Integrated Financial Group, Georgia Plantation Shutters Co., Thomaston Hospice, Gaynes Financial Services, and Karen Lee & Associates, for 21 years. She will tell you she has her “dream career” and wants to be “the George Burns of consulting—I never want to retire!”

In addition to coaching, Madge teaches business management, including sales, marketing, business and finance, employee management, client management, partnership communications, and managing these areas for success. Working with clients across industries benefits each client with the best practices of all industries. Her clients also benefit from her experience working in office management, sales, and sales management in small and large corporations and running her own manufacturing rep firm.

As part of her commitment to continuously working on mastering her profession, Madge continues on an intense weekly coaching program, plus other programs and studies of coaching, human behavior, business management and communication skills. As she continues to be coached in her own business, she gains a deeper understanding of the coaching relationship.

A Landrum, South Carolina native, Madge moved her 7-year-old daughter from a small town to Atlanta as a single mom without knowing a soul. But she saw it as an adventure: Her coach says one of her unique qualities is her dedication and loyalty to her family, friends, and clients…she is a “No Quit Girl.”
