ERDOĞAN M. AKDAĞ FOUNDATION

Dr. Erdoğan Mustafa Akdağ, the founder and president of Yibitaş Holding, began his investments in education, culture, social, and health fields in 1987.

Between 1987 and 1994, considering the necessity of institutionalization for the continuity and expansion of these investments, the Erdoğan Mustafa Akdağ Foundation, a family foundation, was registered and announced in the first month of 1995.

With the establishment of the foundation, the Akdağ Family has made significant contributions and provided substantial services in Turkey’s education, culture, social, and health sectors through various activities and investments of the foundation. The foundation’s mission is to contribute to these fields to support Turkey’s globalization alongside the world and help the country reach a contemporary level of development.

In line with these principles, the Akdağ Family has made both financial and moral contributions, especially to enhance the educational and social development of Yozgat, which is economically and socially underdeveloped.

In accordance with the principles of the Erdoğan Mustafa Akdağ Foundation:

To improve the level of education and training,
To engage in activities for cultural development,
To promote and develop the traditional culture of Yozgat, thereby encouraging tourism,
To establish and enhance health facilities,
Educational institutions, health facilities, social facilities, and vocational training institutions have been established, fully equipped, and donated. Additionally, cultural and artistic events have been organized. The foundation continues its activities today, including providing educational scholarships to many students.
