Vickery, a former USTA junior national champion, has also won three singles and three doubles titles on the ITF Circuit.

Her parents had both lived in Linden, the second largest city in the Caribbean nation of Guyana, and her mother is originally from the small mining town of Kwakwani.

Early in 2015, Vickery won her first two ITF Women's Circuit titles in back-to-back weeks in her home state of Florida, both of which came on clay.
