Northwest Pulmonary and Sleep Medicine

Northwest Pulmonary and Sleep Medicine is an independent U.S. specialty medical practice focused on pulmonary, sleep, and critical care services in the northwest Chicago suburbs. The organization provides diagnostic testing and ongoing management for respiratory and sleep-related conditions, including pulmonary function testing, sleep studies, CPAP-related services, and telehealth-supported care. It appears to operate as a clinical service provider rather than a drug-development biotech or pharmaceutical company. The practice is led by pulmonologist and sleep specialist Dennis Kellar, MD, and serves teens and adults through an outpatient care model with affiliations to regional health systems. For biotech analyst purposes, this entity is best categorized as a healthcare services company, not a therapeutics developer.
