Professional Elevator Inspections (PEI) was founded in 2005 by David Lilja Sr. to meet the newly enacted State of Colorado requirements for QEI inspections and safety tests. As a family-owned and operated company, our goal has been simple, to provide the best service possible to our clients and to create value for them however we can. As PEI has continued to grow beyond our roots of inspections, we ensure that every service we provide is centered around this cause because nothing is more important to us than those we serve. To keep providing the best service for our clients, we continually innovate and invest in the technology to make your life as easy as possible without sacrificing our high-quality standards. We have many things we are proud of here at PEI, but the one thing we are most proud of is our commitment to you.
