"Who are the other organic providers I could work with? My medical document would need to be switched to a new provider. How would I do that? I never received a copy of my medical document, either."
Yes , you can change your LP. What you can do is to request from your previous LP to transfer your authorization to the new LP (as long as you authorization is active and not expired). If you got your authorization through the HelloMD, you will be able to get a copy of the medical document when you log in to your account. I hope it is helpful
