Oliver Phillip Otto is the middle child and only son of Katie and Greg and the younger brother of Taylor and the older brother of Anna-Kat. He is attempting to learn to live the rich lifestyle. He was really snobby and only cared about being rich and preppy in the beginning of the series, but he has become less of a snob since he started dating fellow ballerina Gina.
In the beginning of the series Oliver was very snobby
and materialistic (though not coming from a rich family, like his friends). But in season 2 Oliver starts to care less about money because of his girlfriend Gina. He was also misunderstood to be gay.
