Family Values
Pine State Fire & Security was founded by a father and son duo—Brian and Gregory Thompson—built on a foundation of family values, strong work ethic, and a shared commitment to protecting what matters most. While officially established in 2020, the spirit behind Pine State has been in the making for decades.
In 2024, Maine State Security, a respected life safety and security provider founded in 1990, joined forces with Pine State. Together, they formed a stronger, more comprehensive company with a combined legacy of 35 years serving Maine communities.
Today, Greg Thompson serves as President, leading the company with the same passion and customer-first mindset that helped launch it. Although Brian Thompson is now retired, he continues to visit the field and care for long-time customers, staying connected to the work he’s always loved.
What began as a family-run business is now a growing team of dedicated professionals—each committed to upholding the values that have defined both companies from the beginning.
Maine based. Maine values. A Maine family business. The way business should be.
