Diane Waghorne was watching the news along with the rest of the world on the morning of Sept. 11, 2001. Amid the tragedy unfolding before her eyes, she kept thinking, how was it possible all these people trapped in the burning buildings didn’t have a way to get down safely? The thought didn’t go away in the following days, weeks, or months. Waghorne’s mind was made up. She wanted to do something. She wanted to save lives. Three weeks after the towers fell, she found herself on a plane, on the way to a military manufacturing plant.

Diane’s research led her to a product that helps people descend in dangerous situations. Eventually, Waghorne bought the patent for the military compact descender (MCD) and brought the manufacturing to North Texas. Her business partner, Brent Wise, a 35+ year veteran of the Dallas Fire Department, brings his knowledge of Emergency Response rescue and mountaineering to the industrial world. As a Captain in the Dallas Fire Department's Technical Rescue Team and Urban Search & Rescue Teams, his unrivaled real-world experience is applied to all aspects of Tech Safety Lines. Diane's passion for incident prevention across all industries and Brent's lifelong commitment to the safety of others has set Tech Safety Lines apart as a leader in rescue.
