Roni Ziemba created the Stronger Than Steel photography project four years ago to document the heroic work of firefighters and law enforcement agents in Southern Arizona. She has since devoted over 2,000 hours per year to capturing images of first responders in action. Ziemba's photographs can now be seen in three books and 87 fine art pieces displayed in public spaces like airports and fire stations across Tucson. Her intimate photos have earned praise from chiefs and officials for authentically portraying the risks and sacrifices of first responders. Through building trust with agencies, Ziemba has gained unprecedented access to incidents and training to tell the stories of American heroes through powerful images.
