Eric Loes

Services Manager

Eric Loes is the newest Management Team member having joined Stryker Networks in July 2016. It wasn’t the work itself that drew Eric to Stryker, it was the 19-year relationship he had with co-founder Mark Greene. Through working with and being mentored by Mark, Eric now leads and manages the rest of the Stryker team through the day-to-day challenges of a managed IT service provider. Having lived in the Chicagoland area most of his life, Eric values stability, which is exactly what he brings to the team.
