    Philosophy of Care

    Children are my inspiration and our future. Most pediatric patients suffer from some type of skin disease which can greatly impact their quality of life and limit social interactions. I believe in working with families to find the most appropriate therapy for their child's skin condition. I have dedicated an extensive amount of time to training in pediatrics, dermatology, and research in order to be able to deliver the highest level of comprehensive quality care to my patients. My roles as an adjunct Clinical Instructor at University of California San Francisco and San Francisco General Hospital allow me to continue my passion for teaching and stay involved in cutting edge research, thereby providing the most up-to-date care for my patients.
