A Life Remembered
Obituary
Mark Carlsen, a devoted brother and respected professional, passed away on May 8, 2026, in Clear Lake, Texas. Born on November 9, 1958, in Port Arthur, Texas, Mark lived a life marked by dedication, warmth, and a passion for the things he loved.
A proud graduate of Lamar University, Mark earned an associate's degree in Industrial Engineering, a foundation that would support a fulfilling career. He was employed by MRC Global as an inside sales representative, where he found genuine satisfaction and took great pride in his work.

Beyond his professional achievements, Mark’s personal interests painted a vivid portrait of a man who embraced life with enthusiasm. He found joy in traveling to Mexico, indulged in offshore fishing adventures, and maintained a disciplined workout routine. His affinity for sports cars was well known among friends and family, reflecting a zest for speed and style. For moments of calm and reflection, Mark enjoyed relaxing while overlooking the bay, finding peace and contentment in nature’s gentle embrace.
Mark was cherished not only for his accomplishments but for the special role he played within his family. Remembered as a great brother, he shared a close bond with his sister, Linda Kay Chapman, and his brother, David Lynn Carlsen, both of whom survive him. He was preceded in death by their parents, Charles Emile Carlsen and Audrey Marie (Landry) Carlsen, whose memories he carried forward with reverence.

I will truly miss him as a friend, and he will be greatly missed by the MRC family.

Sending my heartfelt and deepest condolences to Mark’s family during this incredibly heartbreaking time. Mark was truly one of a kind, and his absence leaves a void that cannot be filled.
I want to share one of my most cherished memories of him from my very first day at MRC. The front door was locked, and in that moment, Mark stepped in with kindness and warmth, opening it for me. He welcomed me with genuine compassion and personally walked me to my department and to my director’s office. His comforting words, telling me I would do great, truly eased my nerves and made me feel at home. I will never forget the Christmas goodies I brought in once, and how he would come over every morning, joking that it was running low and I needed to make more. Then there was the munchies snack bin we have. He’d always come by to grab a snack. One day, I jokingly called it “Automation snacks,” and oh my goodness, that turned into a standing joke among a few of us. Mark was always joyful, positive, and full of life. His radiant spirit and kindness will be deeply missed. My heart aches at the thought of losing such a wonderful soul.
Today, I lift Mark’s sister and brother up in prayer as they prepare to lay their beloved brother to rest. May GOD grant them the strength, comfort, and peace during this unimaginable time.
Mark… until we meet again!

My condolences to the family. Mark was a great guy.
I enjoyed the talks and (laughs of course) we would have here at the office. After I had my back surgery
a couple years ago, he would always ask me how I was feeling and often offered advice on things I could do to feel better and help me with my recovery:) Mark was a very caring, funny and genuine person who will greatly be missed for sure.
Prayers for his entire family during this very difficult time.

Mark was such a funny, happy guy. I always loved when he’d stop by our desks asking if we had any food or snacks, or when he’d say, “You need to make more of that snack so I can eat it!” He brought so much joy to those around him and was truly a pleasure to be around.
You will be deeply missed, Mark. Keeping your family in my thoughts and prayers during this difficult time. 🤍

Sorry to hear of your loss! From the little amount of time I got to work with Mark, he was kind and always friendly. Willing to help or lend a hand. Funny too! Never short on stories to tell. So sad to hear of his passing. My condolences to the family.

I am very sorry for your loss and don't have the words to describe how much he will be missed. I met Marcus when Barton and Clif Mock were combined into Nuflo ( 2003 I believe) He was a true friend from day one, always ready to help anyone and always running full speed. He was a good man and great friend!

I met Mark in 1998 when we both started working at Endress & Hauser in Houston. I have worked with him almost the entire time up until 2024. He was a great friend and would have given me the shirt off his back. He was a great friend and we had many arguments and agreements. I loved him like a brother and I will miss him tremendously. I am sorry for your loss as it is a loss I share.
