[1] Uganda's Rugby national team star Phillip Wokorach is Okello’s step brother.

[1] In 2019, Okello was voted the Uganda Sports Press Association male basketball player of the year.

That was before he inspired the Oilers to an unprecedented seventh successive National Basketball League (NBL) title.

[1] During the 2019–20 playoff finals with UCU Canons, the Oilers were missing key players: Stephen Omony and Nigerian import Francis Azolibe.

Yet, Okello insured that the Oilers’ winning run would not end as he led his team to a 4–3 series victory.

[1] Later, he was part of the team for the AfroBasket 2021 qualification games against Egypt, Morocco and Cape Verde.
