Breese, Ill., April 14, 2026 – Poettker Construction Company is strengthening its Data Center and Mission Critical construction capabilities to support clients of complex, high-reliability facilities that require precision, resiliency, and disciplined execution.

Jeffrey Casey, PE will lead this initiative as the firm’s market leader for data center and mission critical facilities. In this role, Casey serve as a strategic leader for initial client engagement through project closeout.

Casey brings more than 20 years of experience delivering and integrating complex infrastructure across data centers, mission critical facilities, power generation, and large-scale industrial and manufacturing programs. A licensed Professional Mechanical Engineer, he has led projects and programs ranging from $17 million to more than $1 billion, with deep experience in critical reliability, uptime, and systems integration.

Casey’s leadership and technical expertise have been shaped by his service in the U.S. Navy as a Nuclear Electronics Technician, where he spent six years managing reactor control systems, conducting division‑level training and overseeing preventive maintenance for critical nuclear equipment. His Navy tenure established the foundation for his disciplined approach, operational rigor, and commitment to excellence, traits that continue to define his professional career.

Complementing his industry experience, Casey holds advanced academic credentials, including an MBA, a B.S. in Mechanical Engineering, and importantly, a B.S. in Nuclear Technology, a degree that strengthens his technical foundation in energy systems, controls, and high‑reliability operations, especially relevant to mission‑critical infrastructure.

Casey has repeatedly demonstrated the ability to lead multidisciplinary teams, manage complex design‑build programs, drive value engineering efforts, mitigate risk, and guide projects from concept through commissioning in environments where uptime is non‑negotiable. His certification as a Professional Engineer (PE) and other industry credentials further augment his capabilities.

In his new role at Poettker, Casey will lead client and partner relationship development, oversee pursuit strategy and conceptual planning, and collaborate closely with project teams to align delivery approaches with client objectives.

“Jeff brings a combination of technical depth, relationship-driven delivery, risk mitigation experience, and strategic leadership in data center developments and mission critical environments,” said Keith Poettker, Chairman & CEO. “His ability to align clients, partners, preconstruction, and operation teams will be instrumental as Poettker continues to expand into data centers and other mission-critical markets.”

Poettker’s approach to Data Center and Mission Critical construction emphasizes early collaboration, disciplined preconstruction, quality control, and reliable turnover, supporting both greenfield developments and work within active, operational environments. The addition of a dedicated market leader reinforces the firm’s long-term commitment to delivering certainty for clients operating facilities where performance and uptime are essential.
