Our Doctors
Jason Mazzarella, DC
With drugless, surgery-free chiropractic care, our goal is to restore function to tissues, motion to the joints, and strength and stretchability to the muscle.
We also look at each patient as a whole rather than as an independent part. Sometimes, taking care of one part of a person, such as their back or neck, resolves another issue in their body, such as shoulder, arm, or leg pain.

Together, we’ll focus on thorough healing, encourage you to become active and help you and your family discover how health and wellness really feels.

Brain Mapping for Concussion

Jun 1, 2022

Brain mapping, is an assessment tool used to measure your electrical activity (brainwaves) in the cerebral cortex (brain). Your brainwaves are accessed through digital technology known as a Brain Computer Interface (BCI) and analyzed through a normative database.

The brain map is then used to aid in diagnosing health conditions by providing a means of statistical evaluation of the electrical activity in the cortex.

Research has found brain mapping to have reliability that is equal or superior to routinely used clinical tests such as mammograms, cervical screenings, blood tests, MRI, and CAT scans for specific conditions. 



New 3D Orthotic Scanner

Mar 12, 2017


We are proud to offer the first 3D foot scanner capable to scan both your feet and your shoes.  ​

Orthotics can be made perfectly, but orthotics traditionally have only been custom made to match your foot, not your shoe.  With varying degrees of arch support in shoes, a perfect orthotic could actually cause you more pain once placed in a shoe.  

This brand new cutting edge technology now allows us to make the top portions of the orthotic perfectly for your foot, while making the bottom portion of your orthotic perfectly fit your shoe.  

Watch how it works here.d
