Diane Elaine (Tacy) Jackson

Diane Jackson, 72, of Greenfield, Indiana, passed away peacefully in Greenfield.

Diane was born in Elkhart, Indiana, to Randolph and Ramona Tacy. She built a distinguished career as a project manager, working for respected companies including Boeing, Rolls-Royce, and Raytheon. Throughout her professional life, she was known for her dedication, leadership, and strong work ethic.

Above all else, Diane was a woman of immense faith who loved her family deeply. She found her greatest joy in time spent with her loved ones and took pride in supporting and encouraging those around her.

She is survived by her husband, Jim Jackson, of Greenfield, Indiana; her son, Myles (Angie) Heckaman, of Chattanooga, Tennessee; and her daughter, Sara (Zach) Reasoner, of New Palestine, Indiana. She is also lovingly remembered by her grandchildren Maddie, Lilly, Ella, Luke, Hayden, and Kayte, who brought her great happiness.

There will be no service at this time. The family will hold a private celebration of life in early 2026.

Diane will be deeply missed by all who knew and loved her.
