About Hollenbeck

Over 40 Years of Experience

Hollenbeck Industries, founded in 2019, might be new, but we have over 40 years of experience on our staff. Our parent company opened in 2012, and over those years, we have evolved. As a family firm, we live out our motto—continuous innovation.

From our beginnings as On The Mark (OTM) in 2012, located in a small office building, we grew to a 30,000 square foot facility. But we have expanded in other more significant ways as well. With an initial focus on munitions manufacturing as a defense contracting company, we are expanding our capabilities into other sectors.

As we expanded our machining capabilities and capacity, we also extended into engineering and design with the goal of becoming a leader in creating the future in technology and manufacturing. Hollenbeck Industries offers a full array of services from research and design to production and assembly.

Our Values

As we have grown, we have never lost sight of the values that are important to us: precision, reliability, service, efficiency and value. Hollenbeck Industries remains dedicated to delivering quality parts, manufactured to your specs, quickly and affordably. We value customer relationships, so we cultivate accountability—transparency and traceability—in all of our transactions.

Above all, we take pride in being able to say, “Made in USA.”
