 She first served the Liberian government in March 2006 as the Special Projects Coordinator for President Ellen Johnson Sirleaf's executive staff.

 In 2008, Broh became the Deputy Director of the National Port Authority.
 In February 2009, she was selected to serve as Acting Mayor of Monrovia in place of the previous mayor, Ophelia Hoff Saytumah, in the President's effort to legitimize the Monrovia City Corporation's (MCC) administrative and financial management.
 Although Broh was seated in February 2009 by appointment, rather than by the usual democratic election process, she was not officially confirmed by the Liberian Senate.

 His published op-ed in the USA Today, titled "Downfall of the Muslim Brotherhood" drew much attention in Washington, and established him as a rising star in the Ministry of Foreign Affairs.

Hilary Richard Wright Johnson (June 1, 1837 – 1901) served as the 11th President of Liberia from 1884 to 1892.
 He was elected four times.
 He was the first Liberian president to be born in Africa.
 He had served as Secretary of State before his presidency, in the administration of Edward James Roye.
The Monrovia clashes in 1998 were the result of Liberian President Charles Taylor's attempts to violently eliminate one of his last domestic political opponents, Roosevelt Johnson, a former warlord of Krahn ethnicity.
 At the time, Johnson still lived with a small loyal militia in Monrovia, the capital of Liberia.
 After some minor armed altercations, almost all of Johnson's followers were finally killed by Taylor's security forces during a major firefight in September 1998, though Johnson himself managed to flee into the United States embassy.
 After one last attempt by Taylor's paramilitaries to kill him there, causing a major diplomatic incident, Johnson was evacuated to Ghana.
 Although the clashes were effectively a political victory for Taylor as he had removed Johnson from Liberia, the mass killings of ethnic Krahn after the clashes contributed to the outbreak of the Second Liberian Civil War which saw the president being toppled.
