I would agree on getting your own healthcare provider, but I’m not so sure about the artwork. I think that if you are ready to cut all the ties with your H, then yes, go ahead and ask for your art to be removed from his office. If not, I would leave it alone. Just my opinion. Unless it represent a significant value and something that needs to be discussed up front in terms of assets.
