Mary Ellen (Sliney) Hart

Maynard, MA

Mary Ellen Hart, Caregiver 

Mary Ellen (Sliney) Hart, of Maynard, formerly of Clinton and Belmont, died Tuesday, May 21, 2024, in Care Dimensions Hospice Residence in Lincoln. She was 84. 

Our Mom passed away peacefully in the late afternoon. It was a beautiful sunny day. Surrounded by family who adored her she was lucid, smiling, talking, looking at pictures, and sharing "goodbyes" in the hours before she slipped away. The staff at Care Dimensions Hospice House in Lincoln was amazing. 

Our Mother began charting the course of an "empowered Woman who can have it all" long before that concept became a more popular rallying cry in our culture. Earning her Nursing Degree at St Elizabeth's Hospital in the late 1950's she started her career. After marrying the love of her life, our dad Jim, she walked away from Nursing and began making our home. She brought Michael, Kathy, Stephen, Kevin, and Sarah into the world and raised us with old school discipline wrapped in the warmest hug you could ever imagine. She then returned to her Nursing career, leading a team of Earth Angels in the "End of Life" space at St. John of God Hospital in Brighton. Close to where she'd begun her schooling all those years earlier.

Five kids in a house is an absolute zoo. When we were very little Mom famously stretched a garden hose across where the end of the driveway met the sidewalk and said, "That's the line". So....there was a line. This stayed with us all our lives and we knew there were lines you shouldn’t cross. There was also a bottomless well of unconditional love, compassion, encouragement, and... food... LOTS of delicious food and homemade goodies.

One might assume that our mother followed the time honored tradition of carrying the environment she grew up around home to us. This was not the case. Mom's upbringing was not a "Peace in the valley" framework. Far from it. So the arc of her story is truly that of "The Comeback Kid". A turn-around expert. 

This spirit carried on through life under a stage 4 cancer diagnosis for over two years. Consistent rallying. The Comeback Kid.  

So... in the end, "Caregiver" wasn't just the nursing career that bookended Mary Ellen's Motherhood. And it wasn't just her safety, strength, deep love, and "be who you are" approach to homemaking....

"Caregiver" ended up being our mother’s all-encompassing lifelong mission. Full measure.

Mission accomplished. Time to rest.
