I have a fabulous doctor. He was recommended by my mom's friend. He is great for ALL endocrin issues. Even if you live in the LA area, HE IS WORTH THE DRIVE!!!
He listens, is considered, NEVER blames the patient, and told me "We will make you better, we will figure out whats wrong with you." And he has. He sees me every three months and does extensive bloodwork. He even gave me his email address in case I have questions.

You have to pay up front and then submit your claim to your insurance. I think he does this so he isn't subject to approval by insurance companies.
