My care philosophy
I am interested in caring for children with medical complexity and helping to coordinate care with other specialists. I believe in a shared decision making model that strives to include caregivers and patients in the decision-making process. I feel it is important to work within the goals that families have established for their children in order to promote health and wellness.
