Mary Ellis, an EMT nicknamed “Delco’s Mom,” has died after a valiant fight with cancer, writes Nicole Acosta for DailyVoice.com.

Ellis was born in Collingdale and had a 30-year career in emergency services.

She was a volunteer at Collingdale Fire Company, then Darby Fire Company, before becoming a Mercy Fitzgerald paramedic and working for Norwood Fire Company.

She was also a CPR instructor.

Ellis worked with fire companies in Sharon Hill, Lansdowne, Folcroft, Yeadon, Briarcliffe, Darby, and Clifton Heights.

“Chances are probably pretty good you met her in one fashion or another, either treating one of your family members or if you needed her services, treating you like one of her family,” the Darby Township Police Department wrote on Facebook.

Ellis brought an “endearing, zesty spunk for life,” according to her obituary.

“Mom was a staple in EMS and was often found chasing her ‘children’ around on fires and other emergencies to ensure everyone was hydrated and cool or warm depending on the weather,” the Darby Fire Company wrote on Facebook.

“Her humor, love, compassion, brutal honesty, and smile will be missed by so many of us.”
