It takes a minute to find words to describe Sr. Marie Joannes whose excellence in science was only exceeded by her humility and kindness. She was also very funny even though it sometimes took a second for her wit to register. She surely was good to me in many ways including conversations over the years about my children and work, life's struggles and hope.

Oh, my original comment was in fact posted. Well, here's another.

It saddens me to learn of Sr. Joannes passing, not death, but it also fills me with gratitude to have known her and been the beneficiary of her kindness, knowledge, and friendship. I was an unhappy 'girl' when I arrived at Barry in 1962, and her life still inspires me to finish my own as best I can. Here's to the nuns and to one especially terrific one whose goodness and excellence will long remain with those who knew her.

Cemetery of the Adrian Dominican Sisters

Our Adrian Dominican cemetery with its circular headstones is a beautiful place of rest for women who gave their lives in service to God—and a peaceful place for contemplation and remembrance. 

We will post memorial reflections on our faithfully departed Sisters and Associates. If you would like to reflect on a Sister or Associate who has gone before us, please send your reflections – no more than 500 to 600 words – to Sister Barb Kelley (

We invite you to meet some of the wonderful women who have recently crossed into eternity.
