Continuing in 2024, he participated in another action of Leirion MUN Academy, the "1st Leirion MUN Conference for Primary School Greek Students," that took place in Leirion Alternative Library, in Cholargos. In 2025, he took a step further by applying to become President of the ITU Committee in the 4th International Leirion MUN Conference in Malta. Dimitris responded to this role in a very mature way, despite his young age.

Dimitris, moreover, is an undetachable member of the Leirion MUN Family. His biggest challenge is to take the responsibilities to be a member of the Secretariat in the 5th International Leirion MUN Conference.
The main reason that led him to this decision is his love for the Organization and his aim to enhance his skills, refine his opinions, learn how to lead a team in an effective way, and deal with issues that may occur in an International Organization.

Dimitris Markopoulos is a talented young man. His journey combines academic dedication, athletic achievements, artistic creativity, and passion for international diplomacy. All those qualities make him a well-rounded and promising person.

He is the perfect example of the ancient Greek phrase "νους υγιής εν σώματι υγιεί," which translates in English as “a healthy mind in a healthy body.” As the ancients said, this combination reaches perfection.
