Mark you were so kind and special to all who knew you. I will never forget our time together you will always be a special memory. Rest in peace and I hope to see you again.

I am Mark's sister and today is 7-19-2019. Mark has been gone for more than a year now. I miss him as if it was yesterday that he passed. He was a beautiful person, a wonderful brother, and a good friend. He was so brave and had so much courage in spite of his illness. He is truly my hero and now he is my heavenly Angel. Mark, I love you now and forever - Rest In Peace and someday I hope we are reunited.

For Jenni, Mark's Family and his friend, Chuck:
We enjoyed Mark's participation at the Yellow Springs Hootenanny - and yours as well. It always brought a smile to see you all come in from Centerville to help raise the roof in song. Mark's joviality, his friendly, welcoming disposition, his harmony - in tunes as well as with others - will be missed.
   The August, 2018 Hootenanny took time to remember Mark - in song and with a few anecdotal stories from Chuck and others. Also, in his rememberance, we pulled together to make a small donation to WilliamSyndrome.org as a tribute to Mark. He will be missed. We wish his family and friends well in this sad passing of our mutual friend. Robert Libecap, YS Hootenanny.
