Looking back at her childhood, Angella's memories of Kenya are blurry. She was only 10 years old when she secured a scholarship to Burundi where she would join an International Tennis Federation programme.
Perhaps that would explain why she speaks with a bit of a French accent, although the young athlete says that she is fluent in Swahili too.
Angella says that the support from the local tennis federation has been good, noting that those around her always pushed her to greatness.
She confirms that she will be joining Auburn University, Alabama, in the Spring of 2023, having already accepted a scholarship offer from the institution.
The tennis player says that she picked the school from a wide list of scholarship offers - indeed, many institutions had noted her promising talent and determination.
"I had help from my coach Francis Rogoi and also the federation, I had 30 college scholarship offers. I shortened the list to five. When I was in the US Open Tournament, I got the chance to visit four schools," she says.
"I wanted a college that will align with my goals so that I can continue with my tennis career. The school I chose, Auburn, was aligning with that; and there are many aspiring professional players there, so I know that I will have a driven and supportive team around me."
She says tennis is a sport that anyone can learn, encouraging youth to take it up and explore their skills.
"I can tell young people that tennis is for all, it does not matter if you have money or you do not, just come and try it."
