Welcome! I recommend joining awdpirates.net. That's the local Colorado forum that will have a lot more localized info to help you out.
However, to answer your question Suba Performance, Super Rupair, Groove Subaru, Go Subaru Arapahoe and a few other dealerships are trustworthy and all should be able to help you out. My go to is Groove Subaru. They've never steered me wrong and have fair pricing.
