Dianne Marie Peterson, 75, of Merritt Island, Florida passed away peacefully on June 4, 2026, after a courageous battle with cancer, surrounded by the love of her family and strengthened by her Catholic faith.

Born on February 6, 1951, in South Bend, Indiana, Dianne lived a life defined by compassion, dedication, and an unwavering commitment to education. She was a lifelong educator whose passion for mathematics and science inspired countless students over the years.

In recognition of her outstanding contributions to education, Dianne was honored in 2004 with the Presidential Award for Excellence in Mathematics and Science Teaching, presented through the National Science Foundation—one of the nation's highest honors for K–12 STEM educators. This award reflected what her students and colleagues already knew: that she was an extraordinary teacher who made a lasting difference in the lives of those she taught.

Dianne was a faithful member of Divine Mercy Catholic Church, where her faith remained a guiding force throughout her life. She also had a deep love of travel and adventure, embracing every opportunity to explore new places and create lasting memories with family and friends.

Above all, Dianne was devoted to her family. She is survived by her loving husband, Gerald Peterson; her son, Corey Peterson, daughter-in-law Anna Peterson and her cherished grandchildren, Aubrey (7) and Preston (3). She is also survived by her sister, Anne Zulas, who resides in South Bend, Indiana. Her love, wisdom and unwavering support will remain a lasting presence in their lives.

A memorial mass will be held on Wednesday June 10 at 1:00 PM at the Divine Mercy Catholic Church, Merritt Island, Florida.

Dianne will be remembered for her kindness, quiet strength, deep faith, and the warmth she brought into every room she entered. Her legacy lives on through her family, her students, and all who were fortunate enough to know her.

"Well done, good and faithful servant." — Matthew 25:23
