Thomopulos served with Stanley, an ENR Top 100 firm, for 51 years beginning as an engineering intern and rising to the positions of president, CEO, and chair of the board. He is an international icon in an industry for which he championed a focus on excellence and ethical practices, bringing him recognition many times over.
His global reach has included engineering projects in more than 35 countries. His firm has executed projects in over 100 countries and achieved numerous milestones, among them sustainably expanding rural electricity in the Philippines, surface water treatment in Jordan, and wastewater treatment in Egypt and Yemen. Stanley also played a crucial role in the reconstruction efforts in Kuwait and Iraq after the Gulf wars and designed a state-of-the-art analytical laboratory for the destruction of chemical weapons in Russia.
Thomopulos’ dedication to improving infrastructure and quality of life globally is highlighted by the aforementioned projects. His leadership and vision have not only driven the success of Stanley Consultants, but have also set a benchmark for the industry.

His contributions have been recognized by numerous organizations, and he has served on several nonprofit and for-profit boards, including the University of Iowa College of Engineering Advisory Board, the University of Iowa Foundation Board, Kansas University School of Engineering Advisory Board and the KU Endowment Association. It was Thomopulos’ leadership and his belief in what it means to be a member of the world community that led many Stanley Consultants engineers to volunteer for assignment in Baghdad, Iraq to rebuild the country during the Second Gulf War.
