My Passion for Healthcare

I went into medicine thinking I would be doing primary care. When I worked in the pediatric unit I knew I'd found my place playing with the kids when making rounds. During my residency I enjoyed working with children with chronic lung problems, including asthma and cystic fibrosis. I spent the early part of my career doing pediatric critical care. However, I found that I enjoyed taking care of patients long-term and changed to just pulmonary. There have been many recent developments in the care of patients with cystic fibrosis and asthma and I love taking care of the patients and the families.
