Dr de Chazal is also at Pulmonary Associates of Southern Arizona ( please see my previous review). He is extremely well versed in all aspects of lung treatment. Explains his plan of care and includes the patient as a partner in their own care. When you are a chronic lung patient you must have a reliable pulmonologist for those times when a crisis comes up. This is that doctor. He is not rushed as some doctors can be, with one hand holding your chart and the other on the door knob. He takes time to answer all of your questions and concerns. Talks to you like you have a brain. Highly recommend! I just hope he doesn't leave Tucson. We need more good doctors here. read more
