Nahas held youth soccer leadership roles with the Capital Area Soccer League since 2004, and also served as assistant and scout for various youth national teams.[3][7] He joined the North Carolina Courage senior team's staff as an assistant coach upon the team's founding via relocation in 2017, working for head coach Paul Riley,[2] and also directed the Courage's U.S. Soccer Development Academy girls' team.[7]
On July 8, 2021, The Athletic reported that Nahas had interviewed for the head coaching role at NWSL expansion team Angel City FC of Los Angeles, California, and was the team's preferred candidate.[8] This report generated criticism from Angel City FC's supporters groups, who posted lists of women candidates to social media and publicly suggested that Angel City FC hire a woman. At the time, NJ/NY Gotham FC head coach Freya Coombe was the only woman working as an NWSL head coach.[9] Angel City FC reportedly eliminated Nahas from contention by July 12[10] and announced the hiring of Coombe a month later.[11]
In October 2021, Nahas became interim head coach of the Courage following the firing of Riley as part of the NWSL's response to the 2021 NWSL abuse scandal.[12][13] He was elevated to the role permanently in December 2021.[3]
