Pediatric residents and fellows rotate through the Division of Respirology to gain broad exposure to respiratory diseases in children. Teaching involves a combination of both didactic and in-clinic and on-ward consults, and teaching around cases while supported by a lean but dedicated support staff. Our team includes a cystic fibrosis nurse coordinator; nurse practitioner in respirology, allergy and immunology; registered practical nurse, physiotherapist, dietician, social worker and child life specialist.


The Division of Respirology delivers care to the pediatric populations in our region through services provided at McMaster Children’s Hospital.
