Tom Kellogg of Spectrum, a guy or gal named Porter in Albuquerque, Mike Melton, and Roland DellaSanta should also get credit for building bikes for national level riders. I know there must be dozens more, but those are the ones I can recall off the top of my head. I don't remember who built Rebecca Twigg's bike(s), but it seems to me she had a custom.
