Since 1985, LSI’s mission has been to meet or exceed our customers’ expectations by delivering professional services while establishing long term relationships with both our customers and employees.  In fact, our first customer from 1985 is still a customer today because our company culture is centered on acting in our customers’ best long term interests.  We view success in how well we help our manufacturing customers improve reliability, processes, and efficiencies as we provide excellence in technical services.

Many of our employees have experience working as plant engineers on the owner’s side.  This provides a unique understanding of operational, production, and maintenance needs.
