(e.g., SAT, MCAT, LSAT, and GRE).

We offer neuropsychological evaluations and non-pharmaceutical treatments useful for individuals with:

Beyond comprehensive psychological testing, we offer neurofeedback and neuromodulation services, which are evidence-based therapies that directly train and regulate brain activity to support lasting cognitive and emotional change. These non-invasive treatments, including tDCS, tACS, and transcutaneous vagus nerve stimulation, complement diagnostic findings by providing a direct path from assessment to intervention.

Our mission statement.

Dr. James Lawrence Thomas, Director of the Brain Clinic, is a licensed clinical psychologist and neuropsychologist specializing in diagnosing and treating adult ADHD, LD, and mild head injuries for over four decades.

​

We provide comprehensive psychological evaluations that illuminate the cognitive, emotional, and behavioral factors shaping each individual's life. Our mission is to translate complex data into clear, actionable insights that empower clients, families, and treatment teams to make informed decisions.
