Gregs Thomopulos was born in Benin City, Nigeria where he attended Government College, Ughelli from 1955 to 1962, following his graduation from Government College, Ughelli, he received an ASPAU (African Scholarship Program of American Universities) scholarship to the University of Kansas where he received his Bachelor of Civil Engineering degree with highest distinction in June 1965, graduating in the top 3% of his class. Following his graduation from the University of Kansas, Gregs Thomopulos joined Stanley Consultants as a summer intern, primarily because Stanley Consultants had a branch office in his native country and had dreams of returning home with the company someday.  It was an unlikely pairing - a young structural engineer from Nigeria working for a small engineering firm in a rural Iowa town.  No one could have imagined that the synergy created from the match would have such an impact on Stanley Consultants and the entire consulting engineering industry.

After working as an engineer for 18 months in the Stanley Consultants, he requested an international transfer so he could be closer to his family in Nigeria.  For the next 10 years, he worked on international assignments, and managed the firm’s Liberia office.  He returned to the corporate headquarters in 1978 as vice president and head of the International Division.  In that position, he was responsible for all operations outside the United States, an assignment that took him to over 35 countries in Asia, Africa, the Middle East and the Caribbean, overseeing the design and construction of infrastructure, energy and environmental projects.

In 1984 he was named head of the Project Division, and was elected president of the firm in 1987, a position he held for 20 years before being elected chairman of the board in 2007. He was elected CEO in 1998. With Gregs at the helm, Stanley Consultants reached new heights in terms of reputation, revenue and profitability, making the Company a formidable contender in the global arena.   Under his sound leadership, Stanley Consultants continued along the path set by his predecessors, making outstanding contributions in the engineering field.  The firm was instrumental in bringing electricity to the Philippines, safe water to Egypt through water treatment, helped to restore Kuwait after the Gulf War, and designed a state-of-the-art chemical weapons destruction analytical laboratory in Russia.

In September 2009, he was installed as president of the International Federation of Consulting Engineers (FIDIC), the world’s foremost consulting engineering association, and became the first U.S. citizen to hold the post in over a decade.  He is the first African and only the fourth American President of FIDIC in its nearly 100-year history.  

Gregs describes one highlight of his career as being featured on the cover of Engineering News-Record magazine, where he was described as a “21st Century World Citizen.”   According to the 2004 article, “Thomopulos is emerging as the company’s chief salesman and a force in global engineering politics on behalf of fairer global market access for U.S. firms.”  During his career, Thomopulos was heralded as the firm’s best marketing tool, much in demand by its professionals to meet clients and sell the company’s talents. 

In 2006, Gregs was appointed a member of the U.S. State Department’s Industrial Advisory Panel (IAP).  As a member of the IAP, he served the Bureau of Overseas Buildings Operations (OBO) in an advisory capacity. 

Gregs retired from Stanley Consultants in 2017, culminating a 50+ year career with the company.  He currently serves on several non-profit boards and committees including the Board of Goodwill Industries of Southeast Iowa and several others.
