Evolving to meet your needs.  Now.

Through our network of neurologists and PA-Cs, we are able to service patients in multiple locations across TN.  With high standards including medical assistants with college degrees, to PA-C specifically trained in neurology; we are meeting the challenges of the ever increasing need for neurological services in our rapidly growing population.

What we believe

In everything we do we believe in challenging the status quo. We believe in thinking differently. The way we challenge the status quo is in our holistic approach to the practice of neurology in a way that uncovers root cause issues resulting in symptoms.

If you’re the type of person who likes getting to the bottom of things in every aspect of your life, we have the neurology practice for you.
