No One is More Passionate About Bringing Life to Your History

Legacy doesn’t just happen. To be influential, heritage must be protected and shared with care and authenticity. Müllerhaus Legacy is a conscientious team of creative storytellers and professional historians. Our passion is helping families and businesses inspire the future by using history to keep their stories and values alive.

US and Brainerd Chemical flags

“Instead of just a written documentation, Müllerhaus is capable of producing a truly human story that captures both the business history and the family dynamics. There’s emotion in what they created for us. I can sit here and get a little broken up just talking about it. If you create a piece in which people are that emotionally stirred, that is a piece of great value.

— Mathew Brainerd
Chairman & Owner, Brainerd Chemical

Understanding & Appreciation

“For Dad, it was a bit of cleansing. It allowed him to get something off his chest so that his story is finally heard in a non-derogatory kind of way. But also tell the story for another generation.”
— Raegen Siegfried, The NORDAM Group
