Maria Costello • February 4, 2022



Maria Costello (born Dora Marie Matthews) passed away on the morning of February 4, 2022.
By her retirement as Executive Director of Crossroads Foundation, San Diego, she had devoted
30 years to supporting women in their recovery from drugs and alcohol. She cherished the
relationships she formed within the community of recovery. The love for her children and
grandchildren was her guiding light.
She is preceded in death by her father (William S. Matthews), her mother (Blanche B.
Matthews), her younger brother (Patrick Matthews), her son (Jonathan Turner), and her
grandson (Jacob Polete). The memory of her will be held in the hearts of her friends and family.
She is survived by her devoted husband (Keith Costello), her brothers and sister (David, John,
and Nancy), her children (James Turner and wife Tina Turner; Carrie Turner), and her
grandchildren (Bailey Polete and Alexander Polete).
She left a legacy at Crossroads Foundation in San Diego and throughout her years there, she
developed friendships that were as dear to her as family. Vickie Brady remained as close to her
as a daughter during her last weeks of life.
We cannot express the depths of our gratitude for LeeAnne Kenney-Lafleur who cared for Mom
as her health faded. She gave beyond her medical expertise; her compassion and love
continues to comfort all of us.
Her sister-in-law, Mary, opened her home and cared for us during our time of grief. Even while
feeling loss, she warmed our hearts and tirelessly gave her time, hospitality, and good cooking.
Out of those who have loved Mom, none were as devoted as her husband, Keith. He was ever
by her side throughout their years together, through illness, the loss of her son and grandson,
and her final days.
There will be a celebration of life, the date is to be determined, so that her family and friends
can gather and keep the memory of her alive.

    Maria…or “southern” Maria as my children know her….was my first forever friend as an adult. We met over 30 years ago in Santee and hung in there through the ups, the downs, and the many all arounds in life. I may have had a hand in her stepping onto the path but she pave the way for me in all the other important areas. She will be missed until our paths cross again. My prayers are with you Carrie, James, Keith, Bailey, Alex, and all her sober sisters. Know she is up in heaven loving on those she missed so dearly and spinning yarns that are making the angels smile.
