About Us

At The Magnolia Building Company, we believe that when it comes to Boulder construction, it’s all about client satisfaction. Building a new custom home is a major life experience that takes a lot of time and energy. As a Boulder general contractor with more than 30 years of combined experience, we believe that this process should be an enjoyable and rewarding one. You should be excited every time you arrive at the job site and see your dream coming together. Simply put, our goal is to be the company we would want to hire – honest, dependable and skilled. Our Boulder builders have the expertise, equipment, and resources to get your job done correctly the first time – and most importantly, in a time-efficient manner. Brian McMahon, the owner of The Magnolia Building Company, has worked in residential construction in the Boulder area since 1995. He started his own company in 2003 and has been growing the company ever since. He enjoys actively participating in this ever-changing industry; learning about and implementing the latest technologies. His mantra "honesty, integrity, quality" is reflected in the projects he completes as well as the relationships he builds with his clients. Ben Beezley has more than 15 years of experience working in the building trades in all phases of construction in both Colorado and California. He is a LEED Associate and holds a BA in Environment and Natural Resources from the University of Colorado. As MBC’s primary project manager Ben has both the skills and knowledge to take your project beyond “green” and create a building that is comfortable, durable, beautiful and sustainable.
