## [Jerry Strabel](https://www.centrisys-cnp.com/key-team-leader-bio/jerry-strabel)

Jerry Strabel started his career by working for the company that built Centrisys’ first centrifuge scroll. Strabel joined the team in 2015 when Centrisys started its in-house machine shop with the idea to control product quality, help with delivery time and lower production costs. These benefits help not only the newly built centrifuges, but also the service department. With his 40+ years of experience, Strabel and his team pride themselves in the fact that since opening the machine shop, not one part needed to service a centrifuge has been outsourced; all parts are machined in-house. In 2018, the machine shop expanded by adding more lathes and mills. This expansion allows the machine shop team to double the amount of in-house machining. “My team give[s] the customer not only the best looking product, but the most precise [product] while saving the [customer] time and money with a quick turnaround,” Strabel says.

 Being in fast-paced situations is a norm for Eric Spiedel, as he spent almost 9 years in the Navy. His Naval experience included being a turbine mechanic and fuel/oil test lab supervisor. These roles provided the training for him to step smoothly into a Centrisys Shop Technician role in 2012. By 2014, he was promoted to Shop Manager, an accomplishment that is his proud of as part of the Centrisys/CNP team. "My Navy experience taught me how to be calm under pressure and how to deal with seemingly impossible situations and deadlines. It also introduced me to many different people and gave me insight into how to interact with different cultures from all over the world," Spiedel said. His team and fellow peers recognized how he over sees the shop team, as he was awarded the Centrisys/CNP MVP of Management in 2015 and 2017.
