Endocrinologist in Houston? Specializing in Auto-Immune?

Have a colleague who has been having issues with an auto-immune disorders for the last two years. She was diagnosed with Graves Disease (which has caused hyperthyroidism).

She currently is on thyroid medicine but she doesn’t think it’s helping. Her endocrinologist will only look at blood levels and thyroid and she does not love him. She feels he isn’t very empathetic or compassionate and is looking for a new doctor.

Want someone who takes Aetna and ideally in med center/museum district… help please!
