For over 20 years, I have served as a pediatric nurse in various care settings. Before becoming a board-certified pediatric nurse practitioner in 2014, I worked in the neonatal intensive care unit as a registered nurse. My first NP position, within a busy pediatric clinic, allowed me to form a strong foundation as a generalist. Then in 2016, I had the distinct honor and privilege to join Columbia University Medical Center (CUMC), working in pediatric urology for 2 years, then moving over to pediatric pulmonology. As a nurse practitioner, I can diagnose, order labs, imaging, and prescribe medication. I treat a variety of pulmonary conditions such as asthma, cystic fibrosis, and sleep apnea. As a mother of 3 children, 2 of whom have had chronic asthma issues, I have deep empathy for the children and families I treat. Education is an important part of the care I provide, and I greatly enjoy the time I spend educating patients and their families. I conduct CPAP desensitization training, asthma education, home spirometer teaching and transition guidance. At CUMC, we utilize a transition program called CF R.I.S.E to help prepare for transition to the adult CF center. I am also involved in quality improvement for sleep medicine and cystic fibrosis. I am proud to be part of a pulmonary team here at CUMC that is always striving to give the best care!
