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.
