  1. I have known “Uncle Mark” my whole life. He was there at my “get go” at Luther Hospital in Eau Claire. He absolutely loved me. He always greeted me with a huge smile and a hug that smelled of garlic….AKA Bear Hug California style. Promptly asking me “how’s it going, Emmy?” And preceded to tell me about his newest construction adventures. Free spirited, health nut and deep thinker. I haven’t seen Uncle Mark for awhile…but I always knew he was out on some venture and campaign. May his next higher spirited travels be filled with fun, food and exploit!! Emmy??‍♀️

  2. My favorite quote from Mark “Hey man everybody knows flowers ain’t no good once they been cut”. I suppose one had to have been there to appreciate the circumstances of that utterance but suffice to say it was the late 60’s. A free spirit with an infectious laugh. Great memories!

  3. Mason, so sorry for the loss of your dear friend. You spent hours with him at the hospital making sure he felt were a good friend to him.

  4. RIP Mark. I am blessed to have known you. Thank you for bringing fun and spirit to each and every day. I appreciate everything you did to make others around you better.
