Dr. Rosenblatt of Dallas. Not sure if he has a private practice,
but he's at adult and children CF clinics and stay's on top of
things. His office at Children's Medical Center of Dallas has state
of the art equipment (the PFT machine they have is brand new, fits
in the palm of your hand, and is very accurate) and every patient
room has Oxy/Air/Vac hookups if you should need it.
