testimonials
“Over a span of a decade I've worked with Matt, Brandon, and Greg on two multi-family projects, two personal residences, and countless other small consultations. During that time, not only did my respect for their design and organizational chops grow immensely, I also realized that they care as much about each of my projects as I do, which has always resulted in a better finished project. I've worked with other architects in Missoula and take solace in knowing that I'll never have to do that again. Beyond their professional skills, they are good human beings who I always enjoy talking with and being around.”
— Duncan McMullin, Missoula, MT
“Working with Brandon and Design Method Architecture has been a great experience. Brandon is responsive, professional, and detail-oriented. He has consistently stepped up to keep the project moving, even in situations where coordination challenges arose outside his lane. His ability to listen, adapt, and provide solutions has been invaluable. I’d recommend Design Method to anyone looking for an architect who not only brings design expertise but also a steady hand throughout the process.”
