Yvonne Fredericks was born to a Kalina family[1] around 1955 in Abrams Creek, located in the Pomeroon-Supenaam region.

Her father, Fred Fredericks, was a teacher[2] and President of the Guyana Organization of Indigenous People (GOIP).

She would ride a bicycle to Anna Regina on a regular basis to take classes at the UG Institute of Distance and Continuing Education.

Pearson's negotiations with the central government and a private company led to the 2002 establishment of an organic pineapple processing facility, which employed over 60 villagers.

Due to new term limits instituted by the 2006 Amerindian Act, Pearson was required to step down as Toshao in 2012.
