Since 1982, we have been the trusted provider of pulmonary care, sleep medicine, critical care, research and clinical trials for residents in northern Colorado.

In addition to providing innovative care for lung diseases, such as COPD, asthma, pneumonia, and lung cancer at our state-of-the-art facilities, our caring doctors provide medical care for critically ill inpatients in the intensive care units of Medical Center of the Rockies and Poudre Valley Hospital.
