First Warning Systems, Inc. (FWS), a Reno-based life sciences software and medical device company, recently retained Joshua D. I. Ellenhorn, M.D., as the Principal Investigator (PI) in preparation for the anticipated clinical validation studies slated for later this year. This is the latest development in FWS’ progress toward the realization of its non-invasive, intelligent, wearable, biofeedback early breast cancer screening device. Retention of an expert PI is a critical step toward bringing FWS’ proprietary breast health product and service to market in the near term.
