Our Approach

Network Spinal Analysis (NSA), founded by Dr. Donny Epstein, is arguably the most advanced research-based neurological and therapeutic approach to chiropractic care and wellness available today.  It is a highly effective, gentle, low-force, non-invasive, drug-free chiropractic technique that reignites the body’s innate intelligence that gives it the ability to self-heal, self-manage its infrastructure, and release neural tension patterns.  NSA empowers human resourcefulness to help our brains and bodies reorganize and develop new patterns of behavior that allow us to become the functional, healthy, vibrant human beings we are meant to be.

The body’s capacity to heal is significantly weakened when the spine is subject to subluxations, misalignments it the spinal column due to physical, mental, or emotional trauma, that cause pinched nerves and interfere with the central nervous system’s ability to connect and communicate with the rest of the body.  Trauma gets stored in the central nervous system as tension and toxic stress that causes pain and discomfort which, when left untreated, turns into life-threatening diseases and conditions.

NSA care reduces those interferences and pressures to the central nervous system via gentle pressure contacts made along the spine that cause a spinal “entertainment” – a gentle wave pattern that travels through the body, allowing the body’s self-regulating resources to recognize and eliminate tension and toxic stress, thereby reducing short or long periods of unnecessary pain and suffering.

“As 21st century humans, we are information overloaded and wisdom deprived. Our nervous systems (essentially our operating systems) are running on centuries old ‘software’ while attempting to keep up with the information demands of modern life. Network Spinal Analysis care helps patients upgrade their operating systems! With more energy and new reorganizational strategies people can transform their health and lives to be more dynamic and filled with greater potential and possibilities.”
