Pediatric Anesthesiologist
Specialties: Anesthesiology, Pediatric Anesthesiology

As a Pediatric Anesthesiologist, it's always a priority to tailor an anesthetic to the needs of the patient and his or her family. Over my years in practice, I've gained a particular interest in the challenges faced by patients with leukodystrophy. Whether an anesthetic is needed for a surgical procedure or to help with imaging studies such as MRI, a child's needs are always changing. It's both challenging and fulfilling to work with families, making a plan that optimizes a patient's experience while minimizing risk related to the effects of leukodystrophies on the different body systems.

HS Assistant Clinical Professor
Department of Pediatrics
Specialties: Pediatric Pulmonology

My interest in the pulmonology/breathing-related care of patients (and families) with leukodystrophies stems from my years working with patients with many kinds of chronic respiratory problems.  Being able to breathe comfortably is one of the most critical components to quality of life, and all patients with neurologic and respiratory problems deserve the support they need to breathe as comfortably as possible.  Patients with leukodystrophies may experience a variety of complications that affect their respiratory system and ability to breathe comfortably including changes in their upper airway tone or strength, difficulty managing secretions and saliva, difficulty with cough, and weakness of the muscles of breathing.  They may also experience difficulties sleeping comfortably and safely.  As the pediatric pulmonologist for the multidisciplinary team, I work with our team members to assure that breathing is thoroughly evaluated, the patient and their family are supported, and any discomfort of breathing is alleviated as much as possible.
