Philosophy of Care

I believe in empowering both patients and families to be a part of the decision making process when it comes to their health decisions. I also believe that medical therapy should not only focus on medications but, where indicated, should address any other concerns that may affect a child's health including nutrition, religious or cultural beliefs, alternative medicine as well as psychosocial health.
