My initial consultation with Dr. Amadeo was mindblowing. I learned about myself and chronic issues I have been dealing with for years. I'm excited for my path of wellness. Alyssa, was so kind and knowledgeable. All-in-all a great experience!
Dr. Amadeo is AMAZING at what he does! He was super intuitive, detailed, and knowledgeable about issues I didn’t even know that I had! This was my first session but I can’t wait to go to the next treatments. I recommend him to anyone with any sort of behavioral, neuro-psychological, or even physical condition.
Dr Waldo & Alyssa truly go above and beyond with their patients. I was fit into their busy schedule last minute. Dr Waldo takes his time to thoroughly examine any issues or new complaints. He knows his stuff!! I love that he educates you on how to make simple life adjustments. So much more than your typical DC office, a holistic functional office that truly does it all. Highly recommend to anyone for anything.
Both! We see children, teens, and adults. Our brain-first approach is tailored to each stage of life, from supporting reflex integration and focus in kids to improving balance, mood, and recovery in adults.
Brain-first care means we start by supporting the nervous system, the body’s control center, before addressing other systems. By improving how your brain communicates with your body, we can help restore function, balance, and resilience. This approach is especially effective for developmental, neurological, and chronic health issues because it focuses on the root cause instead of just managing symptoms.

Payment is due at the time of service; there is no reimbursement available for treatments or services. We accept HSA and FSA cards, and financing options are available to make care more accessible.
Before your appointment, Alyssa will review your concerns, goals, and history to help us prepare for your evaluation. When you come in, you’ll receive a comprehensive neurological and functional assessment to identify the root causes of your symptoms.
Afterward, Dr. Waldo and Alyssa will work together to outline a personalized care plan that supports your specific goals and helps you move toward long-term healing.
