Delta Medical Systems was incorporated in 1979 and grew throughout the 80's and 90's by both organic growth and acquisitions. For more than 40 years, we have been based in Wisconsin, developing and honing our character through our love of inclement weather and long-standing customer relations. What started with a few x-ray installations in Milwaukee and Madison has grown to thousands of medical imaging rooms and suites across the Midwest, and now, the Eastern United States.   

Through our employee dedication of honesty and integrity, we have built a solid reputation of superior customer service. In 2000, we teamed with Siemens Healthineers as an Advanced Partner—a relationship that has proven successful to the benefit of all stakeholders.

Today, Delta continues its growth by expanding coverage nationally as a Siemens Healthineers Advanced Partner. It is a history steeped in field service experience, customer relations, and technologic acumen. Read more

Our Culture 

Our culture is, quite simply, this:

Work hard. Be honest. Be fair. Play hard. Take a vacation. Take a walk. Reflect. Give back. And Repeat. Our culture is collaborative, empowered, purposeful—made possible by assembling a team of talented people with aptitude, fortitude, and personality.

Our robust operational support enables sales and field engineers to concentrate on their role without getting bogged down in minutia. We strive to keep pace, be efficient, and stay relevant. And we remember why we're here in the first place—that thing we must do called work.

Let’s be honest—we’re all here to first provide for ourselves and our family. If we must work, we are blessed to enjoy what we do, where and with whom we do it. Delta enjoys very low employee turnover—approximately 40% of our employees have been with Delta 10 years or more. And the fact that our work positively affects the well-being of others is a nice cherry on top. 

Hear What Our Employees Are Saying...

"Delta has a great group of employees and managers that care about each other and their work performance, which helps everyone succeed. I enjoy the independence and daily challenges associated with servicing high-end imaging equipment and it’s rewarding to know that I'm directly supporting the community’s imaging needs. "​

-Jaret Dedrick, Customer Service Engineer Team Lead  

"Culture is big at Delta. Our motto is work hard and play harder, and it couldn’t be more true. Delta provides a flexible work-life balance, excellent vacation, good benefits, and many other perks that you would be hard pressed to find with other employers. When asked where I work, I proudly respond: Delta Medical Systems."
