Dr. Henley has performed psychoeducational testing for our 18-year-old daughter three times since first grade. Each set of tests informed us of changes with her dyslexia and allowed us to deploy appropriate, actionable interventions. Dr. Henley has a remarkable ability to communicate what his patients need at each developmental stage of testing. He takes time with his patients to help them understand the full scope of the diagnosis while still empowering individuals to be their best selves. Our daughter is now entering a highly competitive honors program in our state university system and we attribute much of her academic success to her relationship with Dr. Henley over the past 10 years.

I have worked with Dr. Henley for over 7 years. He is an outstanding clinician who whose expertise is matched only by his compassion for his clients; many of whom struggle with learning disabilities and related challenges such as anxiety and depression. As an instructor of Academic Language Therapists, Dr. Henley closely tracks the emerging neuroscientific research and practice in learning disabilities, with specific emphasis on dyslexia and ADHD. His vast involvement on research boards gives him insights into best practices and evidence-based diagnostic and clinical practice. As a clinician and clinical instructor Dr. Henley has significantly contributed to substantial improvements in the quality of care for students throughout the Washington, DC area.

Dr. Henley is very experienced and skilled in identifying the cause of academic challenges, making a diagnosis, and in recommending effective interventions. His diagnostic evaluations are thorough, and the detailed report provided to parents is a powerful guide for academic decisions. An evaluation by Dr. Henley is an investment, with long-term value.
