Estes was a Chickasaw Indian Nation member. He graduated from the University of Oklahoma and served in World War II as a Captain in the Army Air Corps 37th Fighter Squadron.

After the war, Estes founded "Architectural House and Plan Business, Nationwide Plan Book" which was to evolve into Hiawatha Estes and Associates.
