Dr. Clementine E. Nanje 2017 – 2021

During the fiscal year 2017 to 2018, the Oroko Cultural Association USA, headed by National President Iya Dr. Clementine Ebenye Nanje, made strides to put Oroko USA in the right direction. The Nanje Administration recorded achievements intended to pave the way for a stronger and more functioning organization.
One of the major achievements was the creation of 501(c)(3) recognition, giving the association nonprofit status, exemption from federal income tax in the United States, and the opportunity to raise funds through donor organizations for humanitarian purposes.
Considering the sociopolitical crisis in Cameroon and Orokoland in particular, the Nanje Administration created a humanitarian assistance committee to address the crisis affecting Oroko communities. The program was structured into fundraising and implementation phases, with committee members carrying out research and investigation on how assistance would be implemented when funds were raised.
The administration also created a think-tank made up of ex-presidents and other prominent members of Oroko USA to provide advice and expertise on projects to be carried out in Orokoland.
The Nanje Administration created an administrative seal for Oroko USA documents, introduced a National Uniform initiative for National Convention use, and launched a Global WhatsApp forum intended to bring Orokos across the globe into closer communication through social, economic, political, and technological information sharing.
The administration also acknowledged challenges, especially fundraising for the humanitarian assistance program, and extended condolences to bereaved families within the organization.

The effort became an international headline and appeared on cable news and in Time Magazine. The girls were eventually freed and able to work and support their relatives back home.
During his tenure, he was a crusader for the Oroko World Conference idea, seeking to create a forum where Orokos in the diaspora and those in the Oroko homeland could meet and craft a way forward for the good of the Oroko ethnic group.

During his tenure, he supported the Oroko Cultural and Resource Center in Kumba, described as “Cameroon Go Operation.” The center operated for over a year and served both Oroko and non-Oroko people.
