Not sure what to say?

My memories of Mark are of us growing up. Little brother of my best friend Liz. I loved all the O´Brien family So sad all the boys are gone. My sincere condolences if I had seen this on time I would have been there to say goodbye to a very sweet guy.

Jon and Jeff I am so sorry to hear of your Dads passing. We always enjoyed Sunday afternoon ribs or pizza at your parents house. He loved showing the kids Jill the deer and was always so upbeat and happy whenever we meet. May the memories you have give you peace at this time.

Grief can be so hard, but our special memories help us cope. Remembering you and your loved one today and always. Mark made such a impact on everything he did. He and I did some work for my Aunt, and also some remodeling of the Waterloo house. I'm also sorry to hear of the passing of Dennis, we were not aware of that. From Joyce and Lois Ackerman Who by the way is still living independently just 7 blocks down the road from me, getting along great just a little slower and able to drive her car...

ALWAYS ENJOYED OUR TUESDAY DISCUSSIONS AT THE CLUB RIP BUDDY
