IRC, Yes, you are right, there are many docs who are not well versed with every aspect of a disease. Many GI docs are too busy running a scope up somebody's colon+ biopsies 10-20x times, per day to do any reading... except for some academic types. Some got a real racket going.
However, HepC is usually treated by Infectious Disease or Hepatologists. Between these folks in an academic type center like an university hospital clinic you should get good tx. A lot of the docs in private practice get antiquated fast.
