I was saddened and shock to learn of Marc's passing. We were roommates during our first year at Yeshiva University. Although we were not the best of roommates (I was totally disorganized), I always considered him a friend. I was especially impressed by his intellect, kindness and patience with everybody who knew him.

My sympathies to Ruth and the entire family.

I was one of Mark's karate instructors. We called Mark affectionately "doc." Doc inspired so many of us by his persistence and insistence on achieving excellence. He never gave up at trying to improve his techniques. His steadfastness was personally inspiring. He was always respectful, and he was very well-liked by all.

As a child of a survivor, Doc and I would have conversations about our parents' Shoah experiences, and he shared several moving memories and artifacts. It was so obvious how much he respected and loved his parents.

Everyone knew Doc as a self-effacing, caring human being. He was the kind of a person who would if needed, give you the shirt off his back.

He will be sorely missed. I am honored to have known him. May you and the family be comforted by Hashem, among the mourners of Zion and Jerusalem.

Hello Ruth,

I had the pleasure of getting to know Mark when he joined our Toastmasters group at CIT. He raised our group to new levels. I learned from him each time he got up to speak. He made me laugh, he challenged me, he educated me, and he inspired me. I will remember Mark as a warm loving man who KNEW how to communicate! I cherish the short time I had with him. Ruth, I am keeping you, Mark, and your family in my prayers.

I wish you much Love and peace. God bless you.

Ruth, while I did not know Mark, I know how tenderly you spoke of him and how you shared your compassionate communication with him. I continue to hold you in prayer and wrap you in my love from Wisconsin.
