Assembly of Turkish American Associations (ATAA), representing over 50 local chapters is the largest, democratically elected Turkish American membership organization in the United States.

Established in 1979 to fight defamation and attacks on Turkish Americans, ATAA has evolved to be the most influential grassroots umbrella organization for the Turkish American community in the United States.

ATAA’s mission is to create cohesion and cooperation between the social and cultural Turkish American organizations around the United States to establish an informed national Turkish American community that can help foster the United States – Türkiye relations and take an active part in promoting a balanced and truthful picture of Türkiye in the United States.

As a non-faith-based organization, ATAA is open to people of diverse backgrounds. ATAA is governed by the Board of Directors with executive responsibility and a Board of Trustees that provides financial guidance and oversight.

ATAA is a tax-exempt, 501(c)(3) non-profit organization that relies on membership dues, private donations, as well as private and public grants.

What is ATAA?

The founding principle of ATAA was the need to create cohesion and cooperation among the large numbers of social/cultural Turkish American organizations around the US. The Assembly’s main goal is to be a link between all communities, large or small, and pursue their interests in Washington and beyond. The main objectives of ATAA are two-fold. One is to create an informed national Turkish American community that can help foster US – Turkey relations and take an active part in promoting a balanced and truthful picture of Turkey in the US. The other is to educate Americans in government, the media and the public at large about Turkey and issues that concern us as Turkish Americans.

In pursuit of its mission and objectives, ATAA undertakes a number of activities, such as annual conferences on contemporary political, social and economic issues related to Turkey and US Turkish relations; educational seminars for Turkish American communities on grassroots advocacy and civic leadership; and cultural events to promote Turkey’s rich traditions, art and heritage.  Working as an information clearinghouse, ATAA regularly publishes reference material on issues that concern the Turkish American community. ATAA e-bulletins, including Community Information Services (CIS), Grassroots Information Services (GIS) and monthly newsletters, reach tens of thousands of readers from the United States to Turkey, as well as many other countries.

Turkish Americans from all walks of life and the business community have benefited directly and indirectly from the work of ATAA in the nation’s capital. The community-building work of ATAA around the nation and its representative role in the nation’s capital have created greater visibility for the Turkish American community and a better image for its members; its educational efforts have contributed to better understanding of Turkey and US-Turkish relations; its vigilance regarding discrimination and defamation against Turkish Americans assure the protection of our rights. ATAA works to create a better future today for generations of Turkish Americans to come.

By becoming a member you will be part of a network of Turkish-Americans and friends of Turkey who care about the historic relationship between the two peoples and who are aware of the crucial role each one of us plays in strengthening the relationship and promoting an accurate and fair picture of Turkey and Turks.
