I hope this works out for you. I have not heard of this doctor either. I don't know anything about this guy so he may be excellent for all I know. But do be aware that being an infectious disease doc or calling themselves a "Lyme specialist" is not a guarantee that they are going to provide good care for Lyme patients. The best way to locate a competent Lyme doctor is through other patients who have experienced successful treatment. He may have had other reasons for asking you to bring your titer results, but beware of any doctor who relies on that for diagnosis. And as Ticker said, ask about testing for co-infections. If he dosen't, run a mile in the other direction. Good luck, I hope this works out for you and you get the treatment you need. Let us know how it goes.
