With solemn hearts, we announce the passing of Mary Katherine Keiran (Boulder, Colorado), whose presence will be deeply missed, having departed on December 31, 2025 at the age of 59. Leave a sympathy message to the family on the memorial page of Mary Katherine Keiran to pay them a last tribute.

She was predeceased by: her parents, Alan Keiran and Barbara Keiran; and her brother Mark. She is survived by: her husband Erik Bernstein of Longmont; her siblings, Michael Keiran (Brenda), Christine Wilson of Longmont, Carol Karim (Saeed) of Niwot, Alan Keiran (Mary Jane) of Lakeville, MN and Scott Keiran of Greenland, NH.; and her nieces and nephews, Zoe Wilson (Clark Sperry) of Arvada, Morgan Wicker (Ryan) of Longmont, Samantha, Madison Keiran of Ipswich, Mass., Michael (Jill), Thomas and Danny of Lakeville Minnesota.

She moved into Erik's house at the height of the COVID-19 pandemic and their quarantine together led to a deep and lasting bond. Following the pandemic, Erik showed Mary as much of the world as he could cram into their calendar.
