In Memory

Diane graduated from John Adams High School in 1975.
Diane was the firstborn child to Duane and Joyce Hartz. She had a wonderful laugh and was so fun and full of life. Diane had many talents. She was a crafter, an amazing seamstress, and made beautiful cards. Her happy place was her kitchen where she made fabulous meal and extraordinary desserts! Di loved being in Siesta Key, FL with her parents and family, and spent every 4th of July there celebrating on the beach. She spent many years cruising with her parents and sister, where she made wonderful memories and lasting friendships with people wherever she went. The last cruise in 2024 was the best with mom, dad, and all four siblings together. Most of all, Diane loved the Lord and had an unwavering faith. She attended Our Redeemer Lutheran Church in South Bend.
Next to God, Di deeply lover her family. She was devoted to her sons and granddaughter. She attended every little league and softball game for her boys and played an important role in helping Brian raise Airis. She loved to spoil her dad and was his “Snoopy Girl”.

Di lived a loved generously and we were all so blessed to be loved by her. She leaves a legacy of deep faith, love of family, and generosity. She was dearly loved by her family and will be terribly missed. We will love her forever and until we meet again, she will live on in our hearts. “Don’t worry about a thing, ‘cause every little thing gonna be alright.”
