In early January, Mack shared that she had been diagnosed with diffuse midline glioma, “an extremely rare type of astrocytoma.”
“It has been a very emotional and challenging time, truly testing my mental fortitude, faith, and physical strength,” she wrote. “They are so positive and we have a sense of calm knowing that my healing is taking place and we will overcome. This experience has brought me closer to God, and I am leaning on him and trust his plan for me.”
A celebration of life will be held August 16 in Ohio.
