Uncommon Experiences
With Uncommon Builders
Advocates. Builders. Catalysts.
As advocates, we look out for your interests. Knowing you have a vision, tempered by time and budget, our experience and skills are put to work. As builders, we bring over 35 years of varied experience to buildings of diverse design and unique features. Exacting craftsmanship characterizes all of our work, while realistic, experience-based estimates and schedules add to your benefit. As in chemistry, we’re catalysts, initiating and facilitating a process. Clear communication between owners, architects, engineers, building departments, and our team is best practice. We strive to keep projects on track to achieve a finished product that best reflects your goals.

“In my 30 years as an architect, I’ve never had a better experience with a general contractor. JMA’s effort was well beyond my own expectations, those shaped from years of working with contractors of all types and capabilities. From early in the design process through property management after construction completion, JMA embraced the process with quiet but effective leadership, and forward thinking in regards to both client and architect needs and desires.”Werner H. Maassen, (former) Senior Associate, Hart Howerton, San Francisco
