I just learned of Mark’s passing last week from one of his ESRI colleagues. I met Mark when he assisted me with learning to use some ESRI tools and we became friends. We lost touch when I changed jobs a few years back. I knew of his illness but did not know it had come back and taken him from us. He was a really nice guy and I enjoyed knowing him. Prayers for your family and for sweet Vivian. I loved hearing about her.

I just learned of Mark's passing. I met him several years ago through a Tourette Syndrome support group. I truly enjoyed our conversations and appreciated every minute of those times. All the best to your family Mark and may your memory always be a blessing.
