Which of these individuals was not an advisor at any point?

Nnamdi Adindu is identified as the correct answer because he is generally recognized in the context of the MADDRAMA framework as having a significant role beyond being an advisor, whereas the other individuals listed have been identified in records and history as having advisory roles at various points in the program. This implies that Nnamdi's contributions may have been more focused on other capacities, such as direct engagement with students or program implementation, rather than fulfilling an advisory position. Therefore, his distinction highlights a different form of involvement compared to the others, who have played advisory roles in shaping the program's direction and impacting its mission.
