A graduate of the acclaimed Studio 58, he started out as a theatre actor, but eventually found himself moving into voice acting full-time.

Most well known for his role as Vegeta, Yajirobe, and Vegito in the Ocean Studios English dub of the anime series Dragon Ball Z, Drummond tends to be cast as either an impassive warrior (Andrew Waltfeld), or a kind-hearted father-figure (Reverend Malchio).

Lately, he has also played the role of the cowardly Yuna Roma Seiran in Mobile Suit Gundam SEED Destiny as well as Ryuk in Death Note.

It appeared in the 21st Dragon Ball Z dub episode, titled "The Return of Goku", which originally aired on American television in 1997.

His daughter Brynna voiced Babs Seed, the cousin of Apple Bloom and her siblings, on the television series My Little Pony: Friendship is Magic, a show which Drummond also appears in.
