I also go to this clinic, and would highly recommend you look at the adult CF center (Warwick practiced in the peds CF department) - I see Dr. Dunitz.
The clinic has a really great atmosphere, and the specialists are knowledgeable in adult issues that affect us. When I saw Warwick, all that was ever discussed was the vest, now I get advice on all areas of my life that are affected by CF. I feel much more in control of who I am and the resources available to keep it up.
