Jon started in the EMS industry earning his EMT patch in 1994. Over the next two years he worked in EMS and joined the Trinity family in 1997 as a full-time dispatcher. Although he truly enjoyed dispatching, he found himself on the ambulance working as an EMT. Jon’s knowledge of EMS and technology grew throughout the years and in 2013 was promoted to Dispatch Manager for Trinity. His leadership in dispatch shined and his innovative thinking awarded him another promotion in 2015 as Director of Communications and IT.

Jon has represented Trinity at a Town, State and Country-wide level as an expert in EMS technology and systems. Jon has been a topic presenter at various industry events. In 1998 he was named the NorthEast EMS Region 3 EMS Dispatcher of the Year. Jon served as a Military Policeman with the Massachusetts Army National Guard from 1990 to 1996. He also holds a degree from UMass Lowell in Criminal Justice.

In September 2018, Jon presented overseas in China  at their Ambulance Forum where leaders from across China and the World gathered to discuss emergency care.
