Areas of Interest: Inspired by experience as an individual with Tourette syndrome, I have dedicated my career to improving quality of life and treatment options for people with movement disorders. I utilize a team approach to care — involving physical therapy, speech therapy, social work and other important services. Most importantly, I involve my patient and their caregiver in decisions about their care. In order to identify more effective and better tolerated therapies, I frequently involve my patients directly in clinical trials conducted at our Institute.
