My brother, who goes by "Tom," changed his name from "Thomas" to "Thom" (pronounced just like "Tom"). He was working in the corporate world at the time, and reasoned that this would make him more memorable. (Unnecessary, probably, as he was a standout in his job performance and personal skills.)

Oh, man, if I worked with him, I'd be pronouncing it just like it's spelled - same consonants as "thumb." There's no reason to go gumming up a perfectly good name.
