We focus on advancing the life safety and security of businesses and governments, and ensuring the security of key assets—people, property, products and reputation.

The Oliver Way


In 2005, I had the honor of becoming the 4th President of OLIVER Fire Protection & Security, marking the start to the third generation of Oliver family leadership. Grounded in the ideals set forth by my Grandfather Leland Oliver in 1957, the core principals of the company are clear: assemble, train, and nurture an exceptional team of people; deliver an unsurpassed level of service; and take pride in everything we do – our name is on it.


Every business is only as good as the people who deliver exceptional service to customers and employees alike. Our people are the best in the industry. We thrive on the ability to learn new products, join challenging projects, and create solutions to unique life safety demands. The bottom line is that we care about each other and our customers.


We do what we say we are going to do, when we say we are going to do it. Always. Our team is committed to creating a customer experience that makes your life safety challenges easy to handle. 24 hours a day, 7 days a week, 365 days a year…we are here to respond to your call.


Our name is on the product and our reputation is built one day at a time, one project at a time, one customer at a time. The third generation of leadership is committed to a renewed energy around the scope, depth, and area of services that OLIVER will bring to you. As a fully integrated team we can offer you the ease of servicing all your life safety and security needs.

To our existing customers, employees, and friends in the industry–I thank you for your ongoing trust and loyalty in our team. We value your business and partnership.

With Appreciation, President, David S. Oliver


Leland Oliver founded Oliver Sprinkler Company in 1957 with a staff of six working out of his home. The firm prospered under Leland’s leadership, quickly gaining prominent clients throughout the Philadelphia region. Leland established the core values and principles of the firm, which include a devotion to outstanding customer service, competitive pricing, and high-quality products and services supported by skilled engineering, fabrication, and installation teams.

Over the years, all three of Leland’s sons-Bill, Dick, and Bob-joined the business and assumed positions of leadership and responsibility. In 1975, Oliver moved to its current location in King of Prussia, Pennsylvania. New capabilities were added over the years to satisfy the needs of an ever-growing customer base. The daywork department was added to handle smaller jobs and routine maintenance; the inspections department was added to provide inspection services; the road department was added to extend Oliver’s geographical service area; and in 2003, the security division was added to enhance the firm’s services and capabilities.

In 2005, Dave Oliver became Oliver’s fourth president. Dave represents the third generation of Oliver family members to lead the company. Under Dave’s guidance, Oliver has continued to leverage the firm’s core values and expertise to meet the challenges and opportunities of the future.
