Beyer, Mark William

Mark Beyer was a beloved husband, father, grandfather, and longtime member of his community. He passed away unexpectedly on December 8th, 2025 at the age of 74.

Loving husband of Mary for 47 years, cherished father of Matt (Paula Cody) and Joanne (Landen Rentmeester), awesome grandfather of Cecilia and Georgia Beyer and Charlie and Colette Rentmeester, dear brother to Susan (Charles) Baker, friend to many. Mark was preceded in death by his parents William and Jane Beyer and sister Nancy (James) Keeney.

Mark grew up in Racine, Wisconsin, became an Eagle Scout, earned his Civil Engineering degree from UW-Madison and his MBA from Cardinal Stritch University. Mark’s professional journey led him around the world with work experiences that took him to the Middle East, both coasts of the United States and many places in between. He and Mary made their home in Brookfield for the past 34 years. He had many talents and interests with a vibrant creative side as a musician, painter, and crafter of an American Civil War diorama. Mark enjoyed Badger football, canoeing, camping, pickleball, playing his trumpet, fishing, and playing cards. He adored his dogs who were dear and constant companions. His grandchildren were the light of his life.

He made a lasting impact on those around him with his easygoing nature and ability to form genuine connections. Mark had a unique gift for making everyone around him feel welcome and included. He will be fondly remembered for his sense of humor, his fun energy, optimism and devotion to his family and friends. We will honor him by following his example: embracing adventure, not taking life too seriously, and greeting all with open arms.

While we mourn the loss of Mark, we also appreciate the extraordinary life he lived. A gathering to celebrate his life will be held at the Sharon Lynne Wilson Center on January 3rd, 2026 from 1:00 PM to 4:00 PM, open house. 3270 Mitchell Park Drive, Brookfield, Wisconsin.

In lieu of flowers, the family suggests donations to the Elmbrook Humane Society or the Sharon Lynne Wilson Center for the Arts.

See Condolences

A close friend and alum of the Wisconsin Chapter of Triangle Fraternity and always a familiar face at our Badger tailgates, he will be dearly missed

It is difficult to find enough superlatives for a friend like Mark. He brought so much love and friendship to so many people in his brief lifetime. It was easy to see the passion he had for his family and different interests. His toy battle scenes were no match for any museum. We will all miss you very much Mark.

Our breakfasts and Badger football traditions were some of my favorite times. I'm so grateful for the laughter, the conversations, and the years we shared together. You'll be deeply missed and always remembered.

I was so shocked and saddened by the reading of this post! We emailed back and forth a few times before our 55th reunion, and after. One email I rememberd, he stated to make sure to find him at the reunion, that he'd be wearing a name tag, I'm so utterly thankful I met with him there!! We both were in drum corps, Mark in the Scouts, & myself in the Kilties. Visited with him for a while about Drum Corps days gone by at the reunion, plus other subjects! A true gentleman and very kind! I knew him for just a short time, but I will still miss Mark! My immense condolences to his family and friends! May he Rest In Peace & his Memory Be A Blessing! With deep sadness, Lance Petro

Carolyn and I have known Mark for about six years. Mark was on our clay pigeon team, and part of our regular small-stakes poker games. He often won! I admired his Civil War knowledge and his proficiency with the trumpet. Mark was a great friend, community member and family man. The world is a little poorer with his absence and we will miss him.

Peace of mind is a call away. We’re here when you need us most.

Mark leaves me with great memories of fishing in Alaska and trying to play golf, among many others. He is surely one of a kind, big hearted and pleasant to spend time with. Wish we could have enjoyed more adventures together but cherish the time we had.

The shock and sadness of Mark's passing will linger with me until my end of time in this mortal coil. Mark was MORE THAN A FRIEND TO ME, he was like a brother in so many respects. I will always reflect back with a mixture of joy and sadness on our Canadian fishing trips, shooting sporting clays and 5 Stand and annual Badger games/tailgate fun. He was an great friend to have who will be deeply missed by all who knew him.

Matt, our thoughts and prayers are with you and the girls. I'm so glad you made such nice memories with him over Thanksgiving. Peace be with you. Jake and Natalie

Please accept our deepest condolences for your family's loss.
