Steven Edgar Mathiesen, beloved husband, father, grandfather, great grandfather, uncle, brother, and friend, passed away peacefully on April 27, 2025, at the age of 80. Born on May 12, 1944, in Odense, Denmark, Steve was the cherished son of Edith Godine Pedersen and Axel Mathiesen.

Steve spent over 30 years as a dedicated General Operator at Kennecott, where he was known for his work ethic, reliability, and calm presence behind the wheel. He brought the same quiet strength and care to his personal life—always gentle, kind, and soft spoken.

He is survived by his loving wife and partner, Karen Curtis, affectionately known as “KC,” whom he married on October 22, 2008. Together, they shared a deep, romantic companionship for twenty-one years, joyfully playing “Kissy Face” and making lasting memories with their cherished dogs, Bruno, Sofee, and Bebee.

Steve was the proud father of seven children: Troye Dean, Rochelle Blood, Stacey Dean, Krystal Mathiesen Kelly, Kirk Mathiesen, Amber Mathiesen Phillips, and Heather Mathiesen. His legacy lives on through numerous grandchildren and great-grandchildren. He was brother to Lone Stephens, Judy Warner, Paul Mathiesen, and Ron Mathiesen.

In retirement, Steve enjoyed the peace and beauty of Sandy, Utah. He spent his days golfing, playing cards with friends, and enjoying the simple pleasures of life. His quiet humor, warmth, and easy smile will be deeply missed by all who knew him.

A graveside service will be held in his honor on Tuesday, May 6, 2025, at 11:00 a.m. at Larkin Sunset Gardens, 1950 E Dimple Dell Rd, Sandy, Utah. All who knew and loved Steve are welcome to attend and celebrate his life. The service will be livestreamed and can be viewed by clicking the "Watch Services" button above.

Guestbook/Condolences

Dear K C and family , many condolences over Steve’s passing.

I spent about half my childhood years growing up with Steve in the sugarhouse area . There were four of us that were especially close ( myself , Tom Day, Bruce Baird and Steve . I hope he shared memories of these years with you and your family , they were amazing times . Especially, the epic basketball games in his backyard on the court we fondly called “Mathiesen square garden“ . There were so many memories, some of which cannot be shared in this forum. Steve was easy going to a fault and not one to lose his temper. And I can say he was tested to the limit many times , especially when he discovered that I had taken a joy ride in his car one evening while he was asleep in bed . Since many folks knew that it was almost impossible for Steve to be become mean or angry , he was often kidded and sometimes even taken advantage of. But his kindness and love for his friends and family always remained no matter the situation . Those who knew him were blessed .
Wishing you all well in your time of grief and I hope all goes well at Steve’s graveside celebration .

Sincerely , Tom Smith

He stood at six foot six,
As skinny as a rail.
He was a gentle giant,
A friend without fail.

In high school his dad converted,
Their back yard into a basketball court.
Neighborhood kids gathered there,
For pick up games as their sport.

In honor of the gentle giant,
We gave it the name.
Of Mathiesen Square Garden,
And played many a fine game.

We’d also shoot some pool,
Or play baseball over- the- line.
We’d cruise in Steve’s low ride Oldsmobile,
As it rumbled around so fine.

We’d borrow Ron’s old pink Ford,
Late at night with no fear.
Go driving around the valley,
Minus the first gear.

Once we stole a case of coke,
From a Coke truck for a lark.
It was parked behind a convenience store,
Turned out we weren’t too smart.

We’d just played baseball over-the-line,
At the Edgehill Ward b-ball gully,
It was hot and we were all thirsty,
As well as sweaty and smelly.

A close by neighbor watched our caper,
Called the cops with our license plate number.
To our surprise a few minutes later,
We were arrested for our blunder.

I remember Steve’s miracle golf shot on a par three,
It sailed over the green onto the street behind,
Then somehow bounced back over the fence,
Landed on the green and blew our mind!

Steve was a genius at any card game,
At poker it was seldom he didn’t win.
He was a friend ,a buddy, a pal forever,
We’ll miss Math but never forget him.
