This memorial site was created in memory of my brother, Mark Steven Cosner.

Mark enriched the lives of so many. His loss has had a profound effect on our family and so many of his friends, leaving a painful void that cannot be filled.

I invite you to contribute to keeping Mark's memory alive for his young son, Brennan, by sharing your stories, thoughts and photos.

Of one thing I am certain; those of us who loved Mark can count on having the ultimate protector watching over us, smiling down and keeping us safe.


Tributes are short messages commemorating Mark Steven, or an expression of support to his closest family and friends. Leave your first tribute here, and others will follow.
