Philosophy of Care

I feel lucky to say I honestly truly love my job. Getting to know a child and family, and having the opportunity to work with patients and other providers to improve that child’s health is a privilege. My research interest include projects involving the gut microbiome. While clinical applications in this field are still evolving, I enjoy discussing recent findings with my patients and possible therapies.
