Meet the People from Diamond Manufacturing

The secret to Diamond Manufacturing's longevity has been the same for more than 100 years, according to Diamond’s president, David Simpson. “Our extremely talented workers have the expertise and attention to detail that cannot be matched. We invest in our people and collectively they are our family.”

This tradition of developing and maintaining a closely knit, collaborative team extends all the way from our leadership to our sales and customer support teams to our expert engineers and metalworkers.

As you consider your next perforating or fabricating project, we encourage you to visit one of our locations. Many of our employees celebrate 25, 35, or even 45 years of service! They are passionate about precision and performance and strive to exceed customers' expectations by delivering quality work in a timely fashion.

We invite you to connect with a member of the Diamond team.
