Feeling a loyalty because of the care you've received and the lenght of time you've been receiving care from this doctor is understandable. But it is still your body and the choices are yours to make. Maybe it would feel better if you told your current doc that you would like to sign the authorization to release information because you are going to check out Moffit's services. That way all is out in the open. I would think he would support your right to explore treatment options and to decide what's best for you. It doesn't mean you're judging him or his treatment, but that you have an interest in learning more about what's out there and especially from this specialized and highly regarded facility. It's about you and you're worth it!
