After high school, Mo pursued his new found dream as an artist in the entertainment industry. After being signed by an agent, he quickly began to book national television spots for major corporations such as Visa, Nike and Reebok, among many others. These spots opened the doors to some early primetime guest appearances on shows such as NYPD Blue, Becker and Boston Public. Other television work soon followed with appearances on CSI: Crime Scene Investigation, ER and The Shield.
In 2006, Mo was introduced to a much wider audience. He played one of the lead roles in the hit film Gridiron Gang opposite Dwayne Johnson, inhabiting the role of the troubled quarterback "Leon Hayes". The Neal H. Moritz–produced film grossed more than $40 million worldwide.
As Mo became more successful as an actor, he began to build an interest behind the camera. He produced and starred in The Fall which competed at the Cannes Film Festival in 2008. Additionally, he wrote a screenplay No Return with acclaimed movie and television writer Harry Winer. The film is currently set-up at Smash Media. Since 2012 he has had a recurring major guest role in the FX drama Sons of Anarchy.
In 2010, Mo appeared in Carmen Madden's film Everyday Black Man. Also that year, he recurred on the ABC drama Detroit 1-8-7 as Pooch and also filmed a lead role in the indie film The Deadliest Lesson opposite Penelope Ann Miller and Yancey Arias.
In total, Mo has appeared in over 30 film and television projects over the past decade.
He currently resides in Los Angeles.
