I'm in West Phoenix and I haven't found a good dealership that I trust much.
If I had to use a dealer, I used the one in Suprise AZ. They're much smaller than most around here, so figured it would be easier to build a relationship with them. They worked on my car twice for recalls and I had a good experience with them both times.
Otherwise I do all my own work. For that, I use:
https://www.moparwholesaleparts.com/
For parts. That website is actually the sales counter at the Larry H Miller Dodge dealership in Avondale, AZ. Usually great prices on parts and service items and they're almost always in stock, so I just order then drive over and pick it up.
You have to use that website to get those prices though. I've literally stood in front of their parts counter on my phone ordering parts haha.
