Dianne (Powell) Wickstrom
July 24, 1948 – August 7, 2025

Dianne (Powell) Wickstrom, 77, of Littleton, Colorado, passed away on August 7, 2025, in Littleton. Born on July 24, 1948, in Denver, Colorado, Dianne was a devoted mother whose greatest joy and proudest accomplishment was her family.

She lived a life filled with love, energy, and creativity—whether spending time with family and friends, shopping, exercising, working in the yard, relaxing by the pool and beach, enjoying chocolate, or working on crafts. Dianne was strong-willed, caring, and fun-loving, with a zest for life that touched everyone around her.

She is survived by her children: Tami Floyd (Rick Ostring) of Littleton, Matthew Wickstrom (Candace) of Denver, and Amanda Beaman (Dan O’Connor) of Highlands Ranch; grandchildren: Alexandra, Rachael, Grayson, Griffin, and Danny; and great-grandchildren: Araiah, Addy, and Zoey. She is also survived by her siblings: Linda Eck (Steve) of Littleton, Julie Jacobsen (Ed) of Littleton, and Tracy Baker (David) of Centennial.

Dianne was preceded in death by her parents, Floyd and Shirlee Powell, and the love of her life, Marty Koerner.

The memorial service will be held on Saturday, October 4, 2025 at Littleton United Methodist Church at 10:30 am.
