About Us

In 1933, Kistler O’Brien Fire Protection, a Lehigh Valley native, was founded by George W. Kistler Sr., for the purpose of selling and servicing portable fire extinguishers. As fire protection technology grew, Kistler O’Brien Fire Protection added new products and capabilities to continually improve service and become the leader in special hazard fire protection. 

It was our mission to advance life safety in the workplace. We now manage all aspects of fire protection, which include consultation, design, installation, maintenance, testing, inspection and repair. We provide total capabilities in portal fire extinguishers, fire alarm and detection systems as well as many types of fire suppression systems including FM-200, Novec, Ingeren, CO2 and Foam. 

In 1975, George W. Kistler Sr. turned the presidency over to his son, the late George W. Jr. In their leadership, the company grew from just two employees to now over 180 with the support of Eric Blasser, Kistler O’Brien’s current CEO/President. The company has continued its momentum to grow and innovate within the fire protection industry and surrounding communities.

Dedicated to protecting life and property since 1933.
