Brett Hasenmueller

In Loving Memory

Hasenmueller, Brett David

May 3, 1990 - January 24, 2024

Son of Gary Hasenmueller and Gail Badalamenti, and brother of Connor V. Hasenmueller, Brett sadly passed away on January 24, 2023. He was 33 years old and had been living in Moore, Oklahoma.

Brett was born and raised in St. Louis, MO and attended St. Catherine Laboure grade school and St. John Vianney High School. Upon receiving a leadership scholarship, Brett’s college days took him to Chaminade University in Honolulu, Hawaii and University of Dayton in Ohio. He loved and played a number of sports from soccer to baseball, basketball, golf and volleyball. He excelled at everything associated with a ball and was a sportsman a parent would be proud of.

A variety of jobs after college allowed him gain experience that would eventually land him a job with ARS Construction of St. Louis, and after several months, moved to their Oklahoma office as Head Adjuster.

Brett was an energetic, happy and very generous son, devoted brother and friend to anyone he met. His aunts, cousins and friends will remember him as laughing, telling very silly jokes and making everyone feel his warm and beautiful soul. You could always count on Brett to lift your spirits. Compassionate, kind and caring, Brett had the biggest heart and would give the shirt off his back if someone needed it. Brett never met a stranger, had countless friends near and far, and made a difference in every life that he touched. Whether young or old, rich or poor, Brett’s selfless acts of kindness reached more people than we will ever know.

Always the most-fashionably dressed, Brett was a magnetic force that lit up a room. He created fond memories in our lives, including many comical ones that will always keep us laughing.

Brett’s love, kindness and compassion will be never be forgotten. So, in tribute to Brett, smile and laugh often, and be the bright light in the lives of those around you.

SERVICES:  Funeral from Kutis Affton Chapel (10151 Gravois Road) on Friday, February 2nd, 12:30 p.m.  Interment Sunset Memorial Park.  Visitation Thursday, February 1st 4:00 p.m. – 8:00 p.m.  In lieu of flowers, and consistent with Brett’s giving spirit, please make donation to Cardinal Glennon Hospital or St. John Vianney High School.  Random acts of kindness always accepted too!

I was fortunate enough to coach you at Vianney and watch you start your process of becoming a young man. I know I will miss you and the person I knew. But your family will miss you even more!

  13. I was fortunate enough to get to know Brett here in Oklahoma. He definitely lit up a room when he entered it. His love for his family and especially his mother radiated from him. He had a giving heart and made everyone around him feel special. I got called in to work on my birthday one year and Brett found out that it was my birthday and brought me a gift, flowers and turned my day around. That’s just one of many examples of how special he was. My heart along with many others is broken and I will truly miss him.

  14. Dear Gary and Gail,
    Lori and I really don’t know what to say to ease your pain. All I know is that we are here for you if you need anything.
    I always loved it when Brett would come over to the house to visit us (i.e. Lauren), and he was always polite, full of fun, respectful, kind, and he always protected our daughter.
    Even though we haven’t seen him in years, we only have great memories of Brett.
    Know that you raised a wonderful young man who had a very positive impact on many people’s lives.

    Love, Jim and Lori Probst

I cannot fathom the amount of grief you must be going through; however, I’m hopeful in due time you’ll smile and laugh often and continue being the same bright light for those around you (just as you’ve always been) and as written in the beautiful tribute of your son. My deepest condolences to you and yours.

  16. Gail, Gary and Connor,
    As the years pass and you have the opportunity to look back at the impact Brett had on hundreds of people, it will bring you peace knowing that he will not be forgotten. You raised one of the best. Our hearts are with you.

  17. Gail
    We just learned of your loss. Wishing you and your family peace during this incredibly difficult time.
