Dr. Sam McDonald is a family and pediatric chiropractor certified through PX Docs, specializing in pediatric developmental neurology and neuro-integrative care. He holds advanced training and certification in the Melillo Method, a leading approach for addressing neurodevelopmental imbalances that underlie conditions such as ADHD, Autism, Dyslexia, and sensory processing challenges.
Dr. Sam’s passion lies in helping kids overcome the struggles that often go unseen—emotional dysregulation, learning difficulties, anxiety, and behavior challenges—by restoring balance and communication within the nervous system. His care combines gentle, brain-based chiropractic techniques with functional neurology applications that help children build stronger brain connections, better focus, and greater adaptability to life’s stresses.
At the heart of his work is a belief that every child’s brain is capable of change. Through compassionate guidance and individualized care, Dr. Sam empowers parents with the tools, understanding, and hope they need to help their child thrive—without relying on medication or invasive treatments.
