Adam Kristoff, 77, passed away peacefully on October 5, 2026.
Adam was born and raised in High Ridge, Missouri. As a child, he enjoyed watching his father repair watches and he was active in Boy Scouts. He was a fire house enthusiast who took great pride in being a volunteer firefighter. He married his high school sweetheart, Marilyn, and soon after he served in Vietnam. Upon returning home, he got his first job at Dynasauer Corporation, working the line making polyurethane products. He worked his way up to Plant Superintendent and retired after 46 years with the company.
Adam was most proud of his children and grandchildren. He loved being involved in all of their activities and sharing stories about each one of them. He was a gentle, kind-hearted man whose smile said it all. He loved Marilyn deeply.
Adam is survived by his devoted wife, Marilyn (nee Isbell), of 56 years; his loving children, Jeff (Kerri) Kristoff, Greg (Andréa) Kristoff and Amy Lyon; his grandchildren, Shelby Kristoff, Keaton Kristoff, Graham (Sydney) Kristoff, Avery Kristoff, Addy Lyon and Everett Lyon; sisters Jacqueline Thomas and Judy (John) Huebner; brothers and sisters-in-law, Frank (Marlene) Isbell, Brenda (Dave) Ruzicka, and Gary (Linda) Isbell; and nieces, nephews, other family, and dear friends.
He was preceded in death by his brother, John Kristoff, his parents Adam and Helen (nee Sedovic) Kristoff, niece, Nicole Thomas and brother-in-law Don Thomas.
His family finds comfort knowing he accepted Jesus Christ as his Lord and Savior and is now in His loving arms.

Marilyn. I am so sorry to hear about Adam’s passing. My deepest sympathy goes out to you and your family. May you find peace in knowing that Adam is now in the arms of the almighty God.

There are no words to say how special this family is to me, how loved they are and how my sadness with Adam’s passing is only surpassed by my concern for their sorrow.
Adam became a part of my life when he became part of Marilyn’s, about 60 years ago. He is truly one of the kindest men I have ever known.
Our hearts will be a little sadder without his smiling face
The world a bit more empty without his quite grace
We will miss his wisdom and his humor
His calm and warm embrace
But Jesus has opened up his arms
And Adam walked through heavens gate.
You will be missed my friend.
We moved to High Ridge in 1964 when I was in 8th grade. My Dad became the scout master for the Troop 546 in High Ridge and that is when I met Adam. We (my older brother and I) became good friends with Adam and had a lot of great experiences until I left to join the Navy in 1968. Adam and Marilyn were great friends and Adam will be sorely missed. Susie (nee Lipton) and I both extend our deepest sympathy to Marilyn and the rest of Adam’s family – Jeff, Greg, and Amy. You will be in our prayers
Marilyn I am sorry for your loss ❤️
You and your family are in our prayers.
Lyon Family,
I am so sorry for your loss. I will keep your family in my thoughts and prayers.
Adam’s birthday is the day before mine and for years , on my birthday, my phone would ring in the evening and it would be Adam wishing me a happy birthday. I have missed those calls for a while now.
On my last trip back to Missouri Patti and I had a visit with Marilyn and Adam on a nice summer evening. So we took a little stroll through their neighborhood and I took his hand and we enjoyed that summer evening as well as our long friendship..
Ms. Marilyn & family,
I’m sorry to hear of Adam’s passing. We met years ago at the Walgreens pharmacy in Valley Park. He knew my father from working at Sauer machine Co., as Dynasauer was down the block and they worked together.
May you all find peace during this time. My thoughts and prayers are with you.
Marilyn you and Adam were so kind to me after John’s passing over 16 years ago. Adam mowed my lawn for several years after that. Im sorry for Adam’s passing but happy to know he knew Jesus. You often sent some pastries to me for awhile which you baked. I think you and Adam met John at Wellbridge

To the Kristoff family,
We are so sorry for your loss of a man you all loved so dearly. We remember him as kind and easy to talk to the couple of times we met him at our various neighborhood gatherings.
We are thinking of you all and pray you are able to feel peace and joy as you remember him through all parts of your lives.
