From an early age, an interest in higher-level mathematics was encouraged by his father and by his uncle Andrew, who was a retired university professor.
As a high school student, he excelled in mathematics, and in 1973, 1974, and 1975 won the Romanian national problem solving contests organized by the journal Gazeta Matematică.
In 1990, as the Eastern Bloc began to collapse, Andreescu emigrated to the United States, where he first taught at the Illinois Mathematics and Science Academy.
[6] During the 1980s, Andreescu served as a coach for the Romanian International Mathematical Olympiad (IMO) team and in 1983 was presented with the national award of "Distinguished Professor".
The first AwesomeMath summer program was very effective, with noted professors serving as instructors, and mentors and assistants who had performed well at Olympiads.
This circle continues to thrive under his leadership, serving the needs of talented middle and high school students in north Texas.
