About Us

We aren't just providers, we are parents too and we have been on both sides of care for complex kids. It is from our own frustration that we created a practice that parents can trust and progress can be made. All of our providers and staff are committed to providing the expertise you need and the compassion you deserve.



We specialize in helping families navigate the medical comorbidities of multiple complex disorders including autism spectrum disorder, connective tissue disorders, genetic issues, mitochondrial dysfunction, and more. 


We begin by gathering and analyzing each patient's medical history. Additional comprehensive testing is done as needed to fill in the gaps. This gives us the information we need to systematically identify and treat complex constellations of symptoms. Our goal is improved health and quality of life for all our patients.

We believe that the best, most comprehensive care happens when multiple experts in multiple disciplines work together on each case. This collaborative, individualized care approach paired with our unique framework for systematic medical investigation is why doctors across the country send their toughest cases to our clinic.
