Sad news – a loss for our community

Dear Friends –

It is with profound sadness that we share that Mary-Catherine Deibel, President of the Harvard Square Business Association, Director of Development at the Cambridge Center for Adult Education and former co-owner of the legendary UpStairs on the Square, passed away last evening after a struggle with liver disease.

Mary-Catherine was a much loved, respected and admired doyenne of Harvard Square.

We extend our sincerest condolences to her husband, Reid Fleming, her family and all those who love her. 

May she rest in peace.

Denise, Bill and Amanda
The Harvard Square Business Association
