  1. Ardith, Robin and family. I was sorry to hear about Duane. Your family was very kind to me in my teen years. I could always feel the love and kindness of your family dynamics. Thoughts to your family as you move through this difficult time.

  2. Robin- I am so sorry to hear of this loss. I have very fond memories of growing up with him around and also being my favorite dentist ever!! My sincere sympathy to you and your family.

  3. Ardie, Robin and family. Bob and I were shocked and saddened to hear of Lenny’s passing. We still think of him as being so active…fishing, hunting, biking etc. Lenny was a great boss to work for as well as being a wonderful friend. That includes you too, Ardie. Prayers are ongoing for all.
    ❤️ Bob and Jane

  4. I read of Duane’s passing, and I offer my condolences to his family. By way of introduction, this is Michael Galeski. Duane (or “Dewey” as we addressed him) and I were good friends in the UMD Music Department. I sang in the choir and was a pianist. I remember many wonderful conversations and times with Duane (as well with another friend, John Wilson), including one time that he invited me to his family home and we baled hay — no easy task for me. Duane was a highly moral and kind person, and, again, I was sorry to hear of his passing. Unfortunately, he and I had lost contact with each other, but I have always had high respect for him and thought of him over the years. Peace to his family.

  5. Sedona misses our Mn. Snowbirds. Many warm memories with Lenny and Ardie. His musical talent is missed at church. His sense of humor is missed at dinner parties. His love of life and God’s people demonstrated a life well lived.
    Love, Sharon

  6. So sorry to hear of this. I just ran across a picture of Duane, my brother David, Steve and me.
