For Teresa Ehnert, leadership has always been about presence—being where the crisis is, standing where decisions must be made and ensuring that when systems bend under pressure, they don’t break. Her journey through public service, including a distinguished career with the U.S. Air Force, prepared her not just to respond to emergencies but to build frameworks that withstand them. At the Arizona Department of Health Services, Ehnert now serves as federal liaison for public health resiliency, environment and policy, where she brings precision and a public health ethos to one of the state’s most critical departments.
What sets Ehnert apart is her ability to navigate the intersection of strategy, safety and service. As a 2025 Titan 100 Honoree, her recognition speaks to a lifetime of impact. She doesn’t just lead programs—she constructs readiness from the ground up, ensuring every plan has a purpose, every action has consequence and every voice in a crisis is heard.
The past three years have tested even the most fortified systems. During that time, Ehnert played an instrumental role in advancing Arizona’s health infrastructure. From overseeing emergency response readiness to rethinking how agencies communicate with the public, she has been a catalyst for both procedural evolution and cultural change within state government. Her focus on operational excellence has helped agencies respond faster, coordinate better and serve with greater empathy.
Ehnert’s vision for the future of public health doesn’t rely on hope—it depends on data, preparation and trust. She advocates for building capabilities across communities, not just institutions. That means strengthening collaborations, expanding training and embedding resiliency into everyday operations. The success of those efforts can be measured in both efficiency and lives saved.
What fuels her work is a blend of purpose and precision. Ehnert approaches each challenge with discipline learned over decades and compassion sharpened by real-world stakes. She’s driven not by protocol alone, but by the belief that every safeguard she helps build protects someone’s family, home or future.
Her ability to foster calm during chaos is revered. Whether leading during a pandemic, coordinating multi-agency responses to environmental health risks or ensuring compliance in complex federal programs, Ehnert brings clarity where it’s most needed. Her colleagues describe her impact not in accolades, but in outcomes—the systems that function because she’s part of them.
Among her proudest contributions is the integration of community-level resilience planning into Arizona’s statewide strategy. It reflects a belief that true public health leadership is not about hierarchy—it’s about proximity. Being close to the problem. Being ready with the solution.
Ehnert represents a rare breed of leader: one who thrives behind the scenes yet whose influence touches thousands. Her work doesn’t just strengthen institutions—it fortifies the people they serve. In every role she’s held, she has left systems stronger, teams more prepared and communities more resilient. In the language of service, that is the highest measure of success.
