Founded in 1990 and employee-owned since 2014, Roeslein & Associates is a global team of EPC solution providers with modular fabrication capabilities who never stop asking “what more can I do” to make a difference. Ever since the first time that question was asked by our founder Rudy Roeslein more than 30 years ago, it has become the foundation for decades of success. There’s a reason Rudi describes our engineers as imagineers. No matter the type of project, we’re the type of people who embrace every challenge and take full ownership from concept to completion with transparency, integrity and curiosity. 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, and provide the fastest return on capital. As specialists in can making, renewables, traditional energy and modular fabrication, we’re committed to asking more of ourselves with every project to create better solutions for our clients, and the world.
