  • Doug, It is rare that Mary and I are speechless but in this case we are shocked at Diane’s passing. It is times like these that being brothers and sisters through lodge is so meaningful. Mary and I offer our deepest sympathy and we are here if you need anything. God be with you and Diane’s family.

  • Doug , we are so sorry to hear of Diane’s sudden passing . She will be missed, I always enjoyed talking to you both (when I could) when you came into the restaurant . Praying that God would wrap his arms around you and Diane’s family and give you peace and comfort.

  • Diane was a special person, a friend while we were in seminary. I am shocked she died so young. Prayers & love to her family and friends.

  • I was surprised and made sad by word of Diane’s death. I knew her as a grad student at Iowa in the early 80s, and as a colleage after her ordination and service in the Diocese of Iowa.
    Rest Eternal Grant to her O Lord. And my light perpetual shine upon her.
