Jani

Jani Lange Diedam, age 71, passed away on October 30, 2026, in Bradenton, Florida. A beloved wife, parent, grandparent and dear friend, Jani leaves behind a lifetime of beautiful memories and a legacy of love and laughter that will live on in the hearts of all who knew her. For Jani's family and friends, the only way to encapsulate her life is that Jani's smile, laugh and genuine compassion positively impacted the lives of all those she met.

Born in Dayton, Ohio, on March 11, 1955, Jani was a graduate of Archbishop Alter High School ('73), Ball State ('77) and a proud member of the Sigma Kappa Sorority. Jani excelled in her career in sales working for companies that included Procter & Gamble, Schering-Plough, and General Foods. After retiring from sales, Jani's love of animals led her to work briefly as a veterinarian tech.

Jani had a boundless amount of energy. She enjoyed walking, biking, swimming, yoga, boating, art work and going to the beach. And her thumb was always green tending to her plants and keeping her yards perfect. After a day filled with activity, Jani loved curling up with a good book and reading late into the night.

While Jani took pride in her career and enjoyed her various activities, her greatest joy in life was traveling the world with her family and friends. Without a doubt Jani's number one travel partner was the love of her life and husband of 45 years, John Diedam. Together Jani and John explored approximately 40 countries and cruised most of the major waterways of the world, making friends everywhere they went. As the news of Jani's passing has spread, John has heard from friends literally from the four corners of the world.

John understands he has lost much more than a wife. He has lost the love of his life, his partner, his confidante, his soulmate, and his travel buddy. But John also realizes he was truly blessed to have lived 45 years with his absolute best friend.

Jani is survived by her husband John Diedam, sons Jonathan and Jason (Chloe) Diedam, her beloved grandsons August and Jonah Diedam, her sister Patricia Lange (Michael) Murry, her many Diedam in-laws and dozens of very special nieces, nephews, and cousins. While Jani will be sorely missed, her life, love and laughter will live on forever in the hearts of everyone who had the privilege of knowing her.
