The primary mission of Asthma Chasers is to impact the eight counties of North Texas by educating parents, children, and other caregivers about asthma.  We accomplish this goal by diagnosing asthma and developing asthma action plans with our patients from one of our many mobile auxiliary sites.  The mobile sites allow us to be a consistent, beneficial presence within previously under-served communities where asthma is most prevalent and to strengthen families with our support.
