Safety Technology USA Expands Again: Welcoming Two New Team Members
At STL USA, our people are the foundation of our success. Every training program, every safety solution, and every customer relationship we build is powered by the expertise and dedication of our team. That’s why we take great pride in recruiting not just the most qualified professionals in the industry, but also individuals who embody our company ethos of integrity, knowledge-sharing, and a passion for keeping people safe.
As our company continues to grow to meet the increasing demands of the renewable energy industry, we are excited to announce two new additions to the STL USA team: Colby Berry, Head of Technical Training, and Ragnar Hartzheim, Sales and Account Manager. Both bring unique experience, energy, and values that align perfectly with our mission.
Meet Colby Berry – Head of Technical Training
Colby joins STL USA with more than 11 years of hands-on experience in the wind industry. Having worked extensively on Gamesa and Mitsubishi turbines—along with many other manufacturers—his career began as a field support engineer for EDP, where he gained expertise in large corrective and crane work. From gearbox and generator replacements to complex troubleshooting of electrical and hydraulic systems, Colby has seen it all in the field.
Over time, his passion for teaching grew, and he began training technicians in electrical, mechanical, and hydraulic maintenance, as well as turbine schematics and converter functions. This commitment to building a safer and more knowledgeable industry is what brought him to STL USA.
In Colby’s own words:
“My passion grew to share my knowledge gained through the years in renewable energy to build a safer and more knowable-based industry.”
Outside of work, Colby enjoys spending time with his wife Ana and their two children, who keep the family busy with dance and jiu-jitsu. When he’s not with his family, you can often find him training horses or working on projects around their property.
Colby’s extensive field and training background has been central to his career development and reflects his passion for knowledge-sharing and advancing safety in the renewable industry.
Meet Ragnar Hartzheim – Sales and Account Manager
Ragnar brings a dynamic mix of international experience, business acumen, and relationship-building skills to STL USA. Originally from Düsseldorf, Germany, Ragnar moved to the U.S. in 2000 to attend Utah State University, where he earned his degree in business administration and marketing.
After spending 12 years in the NBA with the Houston Rockets’ sales and service team, Ragnar transitioned into the renewable industry. He has since held key roles in procurement, business development, and sales management with companies such as Deutsche Windtechnik, Würth Industry, and Einpart.
Now, as STL USA’s Sales and Account Manager, Ragnar is focused on building strong customer relationships and ensuring that our clients receive the highest level of service and value.
He says:
“Keeping people safe is the number one priority, and I am confident our equipment will do just that. I love working with people, building relationships, and solving their problems while bringing value to my customers.”
Outside of work, Ragnar is deeply committed to his family and community. He and his wife recently celebrated 21 years of marriage and are raising two boys and two girls together. Ragnar is passionate about soccer (both playing and coaching), enjoys music, serves in his church, and loves traveling with his family. He is fluent in both English and German and also conversational in Greek.
His wide-ranging professional career, spanning retail, professional sports, and renewable energy—highlights his ability to thrive across industries while keeping people and relationships at the center of his work.
Growing Together
The addition of Colby and Ragnar reflects STL USA’s continued growth and the increasing demand for our safety training and equipment in the renewable energy industry. Their expertise and dedication strengthen our ability to deliver industry-leading training, world-class service, and the innovative solutions our customers rely on.
At STL USA, we believe that safety starts with people. By continuing to build a team of passionate, skilled professionals who share our mission, we are not only meeting the needs of today’s industry but also shaping the safer, stronger workforce of tomorrow.
Please join us in welcoming Colby and Ragnar to the STL USA family!
