Guardian Fire Testing Laboratories, Inc. was created in 1994 by Joe Pearson and Lalit Kumar – both coming from engineering backgrounds. Since our formation, the world of fire testing has changed frequently and dramatically. At each shift, Guardian has embraced the technological advancements and revised requirements to deliver optimal service to our customers.

While our industry has evolved over the past 25 years, what has remained steadfast is the way we conduct business. To this day, Guardian remains a family-run company, with direct ties back to our founders within our current management group.

What we do Matters. It can Save Lives.

On January 11, 2022, seventeen people were killed when a fire broke out in a high-rise in the Bronx. Investigators concluded that fire safety doors failed. This tragedy should not have happened.

Having properly rated and labeled fire doors and frames can save lives and property. Fire doors must be labeled with the appropriate time-rated flame and smoke spread rating. Fire-rated doors, assemblies and hardware are required for life safety compliance in apartment buildings and most other residential (nursing homes, dormitories, etc.) and non-residential (schools, hospitals, hotels) facilities.

We understand the critical importance of Fire Safety Doors. It’s why we do what we do. Contact Guardian today for a complimentary consultation.

Passing the Torch

In 2020 we announced Drew Pearson would be stepping down from his role as Fire Testing Division Manager while still remaining involved with Guardian as a Consultant. Another year has passed and Drew has decided to “pursue other interests and really retire this time” leaving the Testing Lab in the very capable hands of Daniel Brandel as of January 1, 2022.

Mr. Pearson began his career as a Field Inspector at the company his father Joe co-founded with Lalit Kumar in 1994. By 2015 Drew transitioned to Testing Division Manager and was very active in the industry as a guest speaker, board member and committee member for various organizations. At his retirement celebration co-workers noted, “Guardian would not be the company it is today without Drew. We will miss him personally and professionally.”

Taking the reins from Drew is Dan Brandel. Mr. Brandel is an industry innovator with a passion for Research and Development. As Test Engineer and laboratory manager, he will be responsible for quoting, conducting tests and providing reports. Dan will be the main point of contact for customers helping to make communication more streamlined and efficient. Dan can be reached directly at the lab at 716-877-2760, through Guardian’s toll-free number 888-680-7974, ext. 403 or via email at dbrandel@guardiantestlabs.com.

Please join the entire Guardian family in wishing Mr. Pearson a happy retirement and in welcoming Mr. Brandel to the Guardian team.
