Our Story


Begins with 41 Years of Remarkable Service & Solutions

Mountain Machine Works has been solving complex machining obstacles for satisfied customers since 1982. Founder Bruce R. Tisdale first started MMW as a small job machine shop based on his prowess for problem solving and extensive knowledge in the trade. The company has grown over the years, adding highly skilled engineers, machinists, managers and quality control staff, evolving the company into the modern, well-oiled, full-service operation it is today.

Our Process

With decades of experience providing engineering, designing, welding and fabrication, custom machining, contract manufacturing and on-site machining, we’ve come to learn how to exceed customer expectation not only in quality but also in service.

When you work with Mountain Machine Works, you have one-point project management from initiation to completion. That means you have one contact person who knows everything there is to know about your unique machining needs and is committed to your project. Our dedicated and knowledgeable project managers provide direct oversight so that deadlines are met and rigorous quality control measures are maintained up to the point of delivery—all while maintaining consistent communication with you every step of the way.

Our Mission

To seek out solutions to complex, highly unique, contract manufacturing and machining obstacles, and deliver solutions that exceed customer expectation, while building a work environment that empowers and values employees.

To be the preferred partner in providing complex machine components and specialty part production, while offering innovative and inspiring opportunities for our employees.
