Precision care for children with autism and neurodevelopmental disorders.
Dr. Richard E. Frye has spent three decades advancing the science behind autism — from cerebral folate deficiency to mitochondrial dysfunction — and translating that research into personalized care for families.

As recently featured on CBS Evening News — Dr. Frye was interviewed about his research treating children with autism using leucovorin.

About Dr. Frye
A career dedicated to understanding neurodevelopmental disorders
As a child neurologist, Dr. Frye recognized a general lack of understanding regarding the causes and treatments of neurodevelopmental disabilities. He pursued specialized fellowships in Behavioral Neurology and Learning Disabilities, and in Psychology.
“I found that there were many causes of neurodevelopmental disabilities. Amazingly, some children actually started to improve with simple, safe medical treatments.”
His clinical practice, research, and education are all aimed at systematically diagnosing and treating the underlying causes of disability in children with neurodevelopmental disorders, including autism spectrum disorder.
