Kansas City Mourns Beloved Brewer and Entrepreneur Mac Lamken After Tragic Accident
KANSAS CITY, MO — The Kansas City community is grappling with profound grief following the untimely passing of Mac Lamken, a respected entrepreneur, craft beer innovator, and owner of Diametric Brewing Company. The 38-year-old businessman, known for his creativity, generosity, and passion for bringing people together, tragically lost his life earlier this week in a fatal accident that has left the city’s craft brewing and small business communities in shock.
The accident reportedly occurred during the early morning hours of Monday, November 3, 2025, though official details surrounding the circumstances have not yet been fully disclosed by authorities. Lamken was pronounced dead at the scene after emergency personnel were unable to revive him. The news spread quickly across Kansas City, and within hours, social media was flooded with tributes from fellow brewers, customers, and friends who remembered him not only as a skilled craftsman but as someone who treated everyone like family.
Born and raised in Missouri, Mac Lamken’s love for brewing began as a personal hobby. What started as small-batch experiments in his garage eventually grew into Diametric Brewing, one of Kansas City’s most beloved craft breweries. Located in Lee’s Summit, the brewery became a local favorite, known for its bold flavors, community-focused events, and welcoming atmosphere.
Those who knew Lamken best describe him as the heart and soul of the business — not just its founder, but its personality. He was known to greet patrons by name, chat with customers over a pint, and treat his employees like equals. Under his leadership, Diametric Brewing became more than a brewery; it was a gathering place for locals, a home for creativity, and a testament to his belief in the power of shared experiences.
Friends say that Lamken had an infectious energy and a relentless optimism that inspired everyone around him. “Mac didn’t just brew beer — he built connections,” said a close friend and fellow brewer. “He believed beer should bring people together, and that’s exactly what he did every single day.”
Beyond his role as a business owner, Lamken was deeply involved in the Kansas City community. He frequently partnered with local charities, sponsored fundraising events, and mentored other small business owners trying to find their footing in the competitive industry. His commitment to giving back reflected his larger philosophy — that success meant nothing unless it helped others succeed too.
Lamken is survived by his wife, Emily, and their two young children. Friends describe the family as inseparable, with Mac often crediting Emily as his biggest supporter and creative partner in both life and business. Community members have organized a GoFundMe campaign to support the Lamken family in the wake of this devastating loss, raising thousands within the first 24 hours.
A public memorial is being planned at Diametric Brewing later this week, where patrons and loved ones will gather to celebrate Lamken’s life, share memories, and raise a final toast in his honor.
While Kansas City mourns, one message continues to echo across the community — Mac Lamken’s legacy will live on through every friendship he fostered, every pint he poured, and every act of kindness he inspired.
