New & Established Patients Call

Quality patient care requires careful listening to the patient’s own story of their problem, so as to understand the concerns and goals for care from the patient’s perspective. For care to be effective, the patient must remain an active partner of the entire health care team. The best quality care requires going the extra mile to obtain the best possible understanding of the patient’s condition. I also partner with community leaders and non-profit organizations to further enhance and contribute to improving the care of patients especially those with Cyclic Vomiting Syndrome.
