Mark Sidler Obituary
We are sad to announce that, on March 10, 2026 we had to say goodbye to Mark Sidler in Joplin, Missouri. You can send your sympathy in the guestbook provided and share it with the family.
As Mark departs from this earthly realm, his essence lingers — a whisper on the wind, a ripple on the water — a testament to the enduring power of love to transcend the boundaries of life and death. Though Mark may no longer walk beside us, his spirit lives on in the memories and the legacy Mark leaves behind.

He is survived by: his wife Mary Sidler; his son Philip Keegan; his grandchildren, Mason Kleinsorge and Aubry Kleinsorge; his brothers, Larry Sidler and Steve Sidler; and his niece Jessica Lopez.
