Darrell started teaching various courses such as BLS, ACLS, PEPP, and ITLS. Eventually Darrell became involved in the instruction of initial EMT and Paramedic classes with ACAD. In 2012 Darrell was offered, and accepted the position of Internal Training Coordinator (ITC) with ACAD and then in 2020 was promoted to the Chief Training Officer.
