Summary: I am a practicing physician with an interest in nutritional, biochemical and environmental aspects of chronic illness in adults and children. is a website funded by the Moody’s Corporation and dedicated to empowering families caught in the rise in incidence of autism by providing information technology that helps each child be seen as an individual by creating a detailed, structured, accurate medical record that can be used to track progress and find other closely matching individuals whose experience reveals actionable clinical options. Medigenesis is the parent company of this project and is involved in seeking other applications for its patented information technology applications to improve health and reduce health care costs.
