After 49 years in the AEC industry and more than two decades of leadership, vision, and lasting impact, we are proud to celebrate the retirement of Thomas Berger, Founder of DTR Consulting Services and most recently, Vice President and Senior Principal with ECS/DTR (ECS Pacific).
In 2002, Thomas founded DTR Consulting Services with a clear commitment to technical excellence, integrity, and delivering thoughtful solutions within the building enclosure industry. Under his leadership, the firm grew from a small practice into a highly respected consulting organization, known for its expertise, client trust, and quality of work.
His influence extends far beyond the projects he led. He built a culture grounded in mentorship, collaboration, and high standards, shaping the careers of many professionals across the organization. His ability to combine technical depth with practical insight set a foundation that continues to guide the firm today.
In 2025, he led DTR Consulting Services through its successful transition to ECS Pacific, marking an important milestone in the company’s evolution and positioning it for continued growth.
As he retires from ECS Group of Companies, we recognize not only this milestone but the legacy he built from the ground up. We are deeply grateful for his vision, leadership, and the legacy he leaves behind. His impact will continue to be felt through the people he mentored, the projects he shaped, and the foundation he built.
Please join us in congratulating him on an extraordinary career and wishing him all the best in this well-earned next chapter.
