Founder & President
A Legacy of Commitment and Expertise
ESI’s story began in the early 1960s with John Nardontonia, a pioneer in the security industry whose passion for electronic safety laid the groundwork for a family tradition of excellence. After decades of building trust and expertise through his work with JAN Associates, John’s retirement marked a new chapter led by his son, Mark Nardontonia.
In 1997, Mark founded Electronic Systems Installers, carrying forward his father’s legacy while evolving with the industry’s advances. As president, Mark embodies the values of integrity, precision, and community focus that have defined ESI from the start. Under his leadership, our team has grown into a trusted local resource, serving our neighbors with customized security systems designed to protect people, property, and peace of mind.
