About Us

Chris McMillen


Chris McMillen’s greatest strength is seeing opportunity where others don’t. It’s how Mass was born, and it’s how we grow. He knows marketing is not a magic trick; to be effective, it takes a clear message told to a particular audience in the way they want to hear it. Chris’s expertise is in websites, mobile apps, search engine optimization and all things digital, but he recognizes that these mediums are only the basis of a solid approach to making clients and customers aware and encouraging them to act. Chris is the Hatter at our tea party.

With an abundant knowledge and experience in the design and marketing industry, Chris brings a wealth of knowledge and leadership to Mass Enthusiasm. Chris is a graduate of the University of Arkansas at Little Rock with a BS in Computer Science. He is also a lifetime member of Psi Chi - The National Honor Society in Psychology. In his off time, Chris can be found taking care of his three beautiful children, setting a positive example for students through the Dunbar Mentoring program and being an active participant in local community outreach programs.
