Dear family and friends,
John Harrison
It is with great sadness and a heavy heart that I lost my Mimi, my sweetheart, my soulmate last Thursday morning. She was the love of my life. We shared so many good times while raising our beautiful family together. She was My noodles, & I was her special sauce. I was her Safe Harbor & I will miss her so terribly. I will celebrate her life forever as we raise our children.
My dearest Mimi may you rest in peace. I’m so grateful you are no longer suffering.
I will always love you forever.
Mimi was a mother first and always.
Her love for her family was the quiet current beneath everything she did.
She approached parenthood with intentionality and joy, treasuring quiet mornings, school pickups, and the ordinary, sacred rituals of family life. She offered her sons not only guidance and encouragement but a model of kindness that will shape the men they become.
Mimi’s presence will remain woven into the spirit of this place, into the hearts of her family, and into every life she touched. To know her was to feel welcomed.
A private service will be held for family and close friends.
Rest In Peace, Mimi Harrison.
