He graduated from the Tree of Life Christian Schools and Fort Hayes Metropolitan Education Center in Columbus while living with his mother and sister.

At the time, he traveled and performed as a keyboard player in the Christian music group New Harvest, led by Danny Murray.

In 1997, after East to West disbanded, he called his second cousin, Gary LeVox,[2] with whom he played when they were younger, and convinced him to come to Nashville and provide some harmonies on Michael English's album Gospel, which he was producing.

On March 4, 2010, DeMarcus and his band mates were guest stars on CSI: Crime Scene Investigation, appearing as themselves.

DeMarcus has continued to explore his acting career, appearing in the film A Country Christmas, as well as episodes of ABC's Nashville and Lifetime's Drop Dead Diva.
