The best part of my job is being able to care for and treat children who are dealing with a host of pulmonary illnesses. It is extremely rewarding to spend time with my patients and their parents teaching them about how to manage their illnesses and conditions. In today’s fast-paced world of new medical information and treatment modalities, it is vitally important to have accurate information to read.
