Hi Mary, I couldn't determine for sure, but as Robert suggests, it's likely Champion builders. The community is called Champions in the MLS system, and the original sellers in the history show Champion Village LLC. You can contact Champion Homes direct to verify:
Also, there is often a stamp somewhere on the property, often in the garage, with the builders name/logo and year built.
I can help with any of your Las Vegas Real Estate needs or questions; feel free to contact me direct.
