Mulroy is on the Board of Directors for the Grassroots Reconciliation Group (GRG).<ref>{{Cite web|title=Board of Directors|url=http://grassrootsgroup.org/about/board-of-directors/|access-date=2020-08-10|website=grassrootsgroup.org}}</ref> GRG was initiated as part of a United States Agency for International Development (USAID)-funded program called the Northern Uganda Peace Initiative (NUPI) to reconcile and rehabilitate former child soldiers of Joseph Kony's LRA. After USAID's contract with NUPI ended, co-founders Sasha Lezhnev and Kasper Agger continued helping these communities as a self-funded effort. Since 2007, GRG has worked with 38 groups and reached 2,200 people directly, and impacted more than 5000 indirectly.<ref>{{Cite web|title=History|url=http://grassrootsgroup.org/about/history/|access-date=2020-08-10|website=grassrootsgroup.org}}</ref>
