“As a physician, the greatest gift I can receive is the trust of my patients. More than just the affirmation of my training and experience, I believe this trust is the cornerstone of the patient-physician relationship, which I consider integral to the best practice of medicine.”

“I feel that one of the main roles I play as a pediatrician is to educate children and their parents on how to stay healthy and to help them set the stage for maintaining life-long healthy behaviors. I enjoy forming a partnership with parents and fostering their ability to make decisions about their child’s healthcare together. An educated and empowered parent is a key part of the team where good care is provided for their children.”
