Our Story

  • Hire the very best people and treat them that way.

  • Be the one call solution to handle your life safety needs.

  • Our primary objective is to exceed your expectations and keep you as a customer for life.

Founded in 2006 by Michael O’Rourke and Steven Schlesinger, Tri State Fire Protection, Tri State Hood & Duct and O’Connell Fire have together grown to become a leading provider of fire protection and life safety services in New England.

With over 6,500 customers, Tri State offers comprehensive fire protection services across a variety of industries, including Retail, Restaurant, Property Management, Hospitality, Industrial, Education, and Government. We pride ourselves on the long-term relationships we have developed with our customers by always putting them first, no exceptions. We also invest in our team offering training and mentorship and competitive compensation and superior benefits.

We understand the demands placed on business owners and managers to maintain compliance and protect their employees, customers, and property can be somewhat overwhelming. Our goal is to offer a unique program for each customer’s particular challenges. With one phone call, our customers are able to address all of their fire protection needs, knowing that we are committed to meet or exceed their expectations every day.

In recognition of our reputation across New England, Tri State was acquired by Impact Fire Services, a leading self-perform operator headquartered outside Austin, Texas. The Tri State team is excited to have partnered with an equally high-quality fire and life safety service organization. Impact Fire Services and its sister company Academy Fire Life Safety, a provider of national account services, are owned by AI Fire. Together we are committed to providing a model offering that balances the “best of both worlds in fire protection” – capabilities and scale with personal service and accountability.

John Tierney and his crew at Tristate great to work with! They were punctual, friendly and quick to respond to the multitude of questions we emailed them. Not only did they look professional upon arrival, but they were efficient and hard working all day long. Being a humane society, fire hazards are our worst fear, we can sleep better at night knowing that our heating and dryer vets are hair and dust free and safe for our pets at night when we leave. Not only did they do great work, but one of the employees fell in love with a pair of cats who had been surrendered to us as a pair, he ended up adopting both siblings before the end of their work day-bonus! The Staff, Board of Directors and Pets at the Lakes Region Humane Society our thanks to you!
Megan Fichter, Lakes Region Humane Society
Mr. Wayne, I wanted to take a minute to applaud you employees, Aaron and Ian, who were exemplary in their conduct, manners, language and overall attitude. I was so pleased to be able to work with them. They are a terrific team and I am pleased with the service your company provided to have our HVAC exhaust system cleaned. Please recognize them for great effort in my office. I will be happy to recommend Tri State Hood & Duct, LLC. Thanks again for you time and efforts on our behalf.

Your guys just wrapped up here and we are ready for the invoice. I have to tell you that your crew was terrific. They did a professional job and they understood the difficulty with working around a “secure” facility, especially the police side of the building. Please pass on our appeciation and don’t hesitate to use us a reference anytime.
Chief William H. Sullivan, Town of Rye Fire & Rescue
