About Roeslein
& Associates

We Make All Systems Go

We’re businessmen with vision. We’re engineers with imagination. We’re EPC experts who specialize in can making, renewables, traditional energy and modular fabrication. Unlike most engineering and construction firms, we bring a uniquely personalized modular approach to every project, combined with an endlessly proactive mindset to maximize safety and efficiency while providing the fastest return on capital. In every facility and project around the world, we’re determined to do more for you by asking ourselves, “What more can we do?”

Because the more we put into it, the more you get out of it.

Two Founders. One Vision.

Fritz Dickmann in 1990. What started as a dream shared between two people over 35 years ago has grown into a global company employing more than 1,100 people across four continents.

Get to know our team of humble-yet-hungry employees who continue to live out the vision, motto and “What more can we do” mindset of our founders.

One Vision.
One Purpose.
One Roeslein.

Ownership means being accountable for each one of our projects, our daily decisions, and how our actions and work impact our clients and fellow employees. Each of us recognize the decisions we make every day contribute to our future success.

Our vision is to completely diversify our full-service engineering, procurement and construction (EPC) company into the three marketing verticals of can making, renewables, and traditional energy industries on a global scale.

At Roeslein, we’re Humble, Hungry, Strong, Compassionate and Entrepreneurial. We hold these shared values close to our hearts and demonstrate them individually and collectively on a daily basis. We encourage our clients to adopt them as well to further our team unity and achieve continued success.

Remain Humble. Stay Hungry. Be Happy – If we all adopt the principles of this ethos, we won’t simply succeed. We’ll thrive.

Achieving unity means working together toward a common goal. Our Spirit of Collaboration amongst our employee-owners and our clients has allowed us to reach global leadership status with substantial growth and success.
