John and Rachel Martinez

John and Rachel took a leap of faith while raising four children in a small house in La Puente—with the office phone ringing in their bedroom. In the early days, they didn’t know how they would make it from one month to the next. Rachel worked full-time and continued to support the family and the budding business through that job.

When they could finally afford it, they rented a small office in the City of Walnut. John Sr. brought on two of his brothers, Felix and Icelee—both of whom had experience in the fire extinguisher industry—to help launch the company.

John committed himself to learning everything he could about fire protection. He took classes, attended NAFED (National Association of Fire Equipment Distributors) conferences, and eventually earned his contractor’s license. This allowed them to expand beyond fire extinguishers into broader fire protection services.

Over the years, their children—Becky, Steve, John, and Chris—all joined the business, and Rachel eventually came on full-time as well. Through their hard work, sleepless nights, countless sacrifices, and, most importantly, unwavering faith in God, the company continued to grow.

Today, John and Rachel only come in a few hours a couple of days a week, but their presence is still deeply felt. John Sr. remains a trusted source of knowledge—always ready to answer a question, talk with a customer, or check in with the team. Rachel is still quick to lend a hand around the office, whether it’s answering phones, making deposits, or getting the mail out.They remain a vital part of our story—and always will be.
