If they know how to diagnose parasites be sure to let us know.
Dr. Kevin Cahill in NY doesn't have a website but can be googled. He may be the only doctor in the U.S. that does a sigmoidsocopy scope and examine sample the same day. He spends short amount of time with patients tho so I don't know if I'd fly out to him if he was out of state. ;|
Simon Yu in St Louis also does parasite treatments. He does alternative testing - but prescribes a fair amount of parasite meds which beats the usual doctors.
