BRIAN MUELLER

After graduating, he landed a solar job in Seattle but quickly realized he wanted to move to a place where sun is more abundant and solar excels, Tucson, Arizona. His wife and his three dogs did just that and moved to Tucson in May of 2023. Ever since he has been enjoying the Sonoran Desert and everything it has to offer him.
