I knew John as lab director when we were both employed by the Yankton Clinic. John was a devoted employee and a real asset to the Clinic. I enjoyed working with him. He was always current in his field and was committed to seeing that YC stayed current both in laboratory issues and data processing. Rest in peace John.

I am sorry for you your loss. John was a good friend with whom I had many great conversations and experiences. We shared an interest in computers and we even attended a computer show in Las Vegas several years ago. John was 30 years older than I, but I was barely able to keep up with him as we toured the show over several days. I will miss his visits and the lively conversations we shared.

John was so helpful to me as a Scout Leader. He was someone I could always turn to for advice and help.
