Donna Louise Costello, born on October 14, 1959, in Waterbury, Connecticut, passed away peacefully on May 2, 2026, in Corona, California. She was a woman of remarkable generosity and selflessness, who always endeavored to make everyone around her feel included and valued. Donna’s unwavering strength allowed her to stand her ground firmly, yet she possessed a forgiving spirit and was committed to doing what was right throughout her life.

Donna devoted over twenty years working as a receptionist for a law office, where her professionalism and warm demeanor were evident to all who met her. However, it was her role as a homemaker that she cherished most deeply. Donna found profound joy and fulfillment in creating a loving home environment, an endeavor she embraced with her whole heart.

A lover of the beach, Donna found great peace and happiness by the ocean, her favorite place in the world. She also enjoyed cooking, sharing meals, and spending time with her friends. Her affinity for red wine and Mexican food was well known among those close to her, and she delighted in the simple pleasure of pairing the perfect food with her favorite wine, often sharing these moments with loved ones.

Donna’s greatest joy was spending quality time with her two daughters and her grandchildren. Her daughters, Kayla Moreau and Mandi Glass, along with Mandi’s husband Jonathan Glass, and their children—Jett, Gavin, Brody, Winona, and Kirk Glass— and many more family and friends are left to cherish her memory and the love she so freely gave. The bonds she nurtured with her family were the cornerstone of her life and brought her immense happiness.

She was preceded in death by her beloved parents, Valerie and John Costello, who laid the foundation of her strength and character.

Donna’s infectious laughter and warm presence will be deeply missed by all who knew her. She leaves behind a legacy of kindness, inclusivity, and love that will forever remain in the hearts of her family and friends.

A funeral service to honor and celebrate Donna’s life will be held on May 22, 2026, beginning at 11:00 a.m. at the Green Hills Historical Chapel, located at 27501 S Western Ave, Rancho Palos Verdes, California. The service will conclude at noon. It is a gathering to remember a life well-lived and the indelible impact Donna had on all who were fortunate enough to know her.

Donna Louise Costello’s life was a testament to devotion—to family, to friends, and to living with integrity and compassion. Her memory will continue to inspire those she leaves behind.
