I have 21 years of experience and specialize in the field of neuropsychology, with specific knowledge of traumatic brain injury, epilepsy and criminal defendants. I have published on such topics as epilepsy, traumatic brain injury and criminal defendants, and have testified 21 times on topics such as personal injury, criminal responsibility and medical malpractice. Much of my experience with traumatic brain injury is derived, in part, experience from my work with professional athletes.
