At Marathon Petroleum, we are extremely proud of what we do to make people’s lives better. Our employees and contractors work hard every day to provide safe, affordable energy that supports our economy and standard of living.
HSC is an exciting place – we are in the middle of Michigan, but we are at the heart of the global high-tech industries of electronics and solar energy. Our people are dedicated to making our community great locally and focused on competing globally.
