Tracing the formation of the center would begin with a motivated group of citizens who met at the Dundalk Methodist Church in August of 1966 to consider the development of programs and activities for senior citizens of the community. The establishment of the senior center is officially recognized as March 1967. By February 1969, the senior services fell under the auspices of Baltimore County Department of Recreation and Parks. Two staff people were hired, a Program Coordinator and a Director. As support increased so did attendance and programs.

The group known as The Dundalk Senior Citizens Clubroom established a committee to search for a unique name for the new center. The committee's choice was "at ease" (the opposite of attention). Since 1970, the senior group has been recognized as the Ateaze Senior Center.

In November 1971, the Ateaze Senior Center moved to the Servicemen's Club at Fort Holabird. The new location offered a larger facility including recreation areas, meeting rooms, a kitchen, offices and ample parking. By 1972, membership had increased to 476 and many programs and activities doubled in size. The center was open four days a week. Full-time staffing was provided by Baltimore County.

The Ateaze Senior Center is a vibrant center of community activity providing educational, social and recreational services for members aged 60 and over.
