Kevin K. Brown, MD, Department Chair
Welcome to the Department of Medicine at National Jewish Health.
With the dedication of our faculty and staff, we continue to strive for world-class excellence in our clinical and research endeavors with the Department of Medicine's commitment to Science Transforming Life®.
This dedication is reflected in another challenging and exciting year with the development of our new Cardiac Cath Laboratory, Pulmonary Hypertension Center, and Asthma Program. Additionally, there will be further expansion of our oncology, gastroenterology, autoimmune lung center and non-invasive cardiology programs.
We will continue our excellence in allergy and clinical immunology, critical care and hospital medicine, environmental and occupational medicine, mycobacterial and respiratory infections, sleep and behavioral health sciences, rheumatologic diseases, pathology and laboratory sciences and general pulmonology.
The Department of Medicine is committed to leveraging the talents of individuals from all backgrounds. We strongly believe that the recruitment, advancement, and retention of a diverse and culturally competent faculty enhances our research, teaching and patient care mission.
