Lindsay was afforded the opportunity as part of the UCG to represent Pennsylvania at the National Governor’s Association Opioid Data Roundtable in 2018. As Senior Project Manager, Lindsay oversaw the “Naloxone for First Responders Program” in Pennsylvania, which, over the course of a year was responsible for providing more than 60,000 doses of naloxone to first responders resulting in approximately 6,000 overdose reversals.
