What Our Clients Say

Our Association with VSI has more than met our expectations. This family-owned company continuously strives to achieve the highest quality through their quality assurance audit. The owners have daily, hands-on involvement. If an issue arises, their sense of urgency to rectify it and prevent a repeat occurrence is stellar. Their experienced, hands-on management and their compliance with the ISSA Cleaning Industry Management Standards solidify them as leaders in the industry.

Rob Folck Environmental Services Manager UnityPoint Health - Methodist | Peoria November 29, 2016

Our agency doesn’t represent the traditional office setting that most cleaning companies encounter. We occupy 16 facilities that are a combination of old and new structures, from residential group homes to apartment-style living to medical treatment settings to traditional offices. For years, VSI has shown us tremendous flexibility in meeting all of our varied needs. I also appreciate the open lines of communication and the continued support of the VSI management and staff.

Gigi Macklin Purchasing Agent Human Service Center November 29, 2016

VSI has performed exceptionally well here at the Gen. Downing Peoria International Airport. We constantly receive feedback from our passengers about how clean and well maintained the terminal building looks. In addition to the challenges you’d expect with a 125,000 square foot building, working in an airport is a little different due to security rules and changing passenger flows. VSI really stepped up to the plate with the challenges posed by the Covid pandemic. One of my better recent surprises was finding that VSI had already been using anti-viral cleaners before the crisis as a normal course of operations. We’re very happy with VSI, and they are an important part of our team.
