We have seen Dr Rao since our onset back in late 2013. He is very knowledgeable on PANS/PANDAS and spends a great deal of time with patients. This being said, you often have to wait a long time to be seen in the patient room. However, as long as he is spending time with us and being thorough (which he does), I dont' have an issue. Just be prepared to wait or plan to get an early appt in the morning. The staff is helpful, especially Lori, and we have been pleased so far.
