"Sleep issues have such a varied and far-reaching affect on patients - in their personal lives, the lives of their families and friends, their jobs, their past times... I am always glad when a patient has come in to see us at the sleep clinic, there are so many ways we can help. I am honored that patients trust us with their care.

"I believe that it is important to recognize the unique needs of each individual child in order to provide the highest level of care. I strive to provide compassionate care in a child friendly environment, where education and communication form the basis for crafting a treatment plan that is as individualized as it is effective. My patients are treated as children first, and then as patients - this is the cornerstone of my practice."
