About Us

PeriRx, LLC is a premier developer of breakthrough, non-invasive, oral diagnostic technology that will help clinical professionals detect and treat diseases sooner and enhance the practice of wellness management. Our Broomall, Pennsylvania based company was founded in 2008 by Stephen M. Swanick to explore, innovate, and develop novel therapeutics or devices focused on the oral inflammatory/systemic connection. The PeriRx executive team consists of President, CEO and founder Stephen M. Swanick, an entrepreneur and experienced drug and device development professional; Dr. Neil Gottehrer, a practicing dentist; and Dr. Jack Martin, a cardiologist. PeriRx obtained its patented and patent-pending technologies from inventor Dr. David Wong’s firm RNAmeTRIX and the Regents of the University of California, in Los Angeles. PeriRx and RNAmeTRIX have ongoing agreements, which ensure the continuing research and development necessary to advance product development from clinical trial, through regulatory approval, and into commercialization under the SaliMark™ product brand.


PeriRx is committed to improving the quality of patient healthcare through the development of advanced, scientifically-validated, proprietary salivary diagnostic technologies. We will accomplish this by providing reliable, safe and cost-effective molecular DNA tests that aid clinical professionals in the early detection and practice of disease management. Our ultimate goal is to contribute to improved clinical outcomes by helping professionals treat diseases sooner.
