"Tim’s team at O’Neill has been a great partner for IAC. They are extremely knowledgeable of the products and their respective markets.  They are an extremely hard working & diligent group. Very high praise goes to O’Neill Engineered Systems…" ~ John Searson, IAC Acoustics  

"The City of St Paul asked us to hire a sound engineer to tell us the noise levels of our air conditioning units.  We found Chris and he volunteered his time and service to test and estimate the space to report to the city for us. I wanted some acoustic tiles for this community room for some time and he gave us so many choices, made sure that we were comfortable and came back at our convenience.  Really kept us informed every step of the way all the way through the project.  He did the work himself and gave us free labor for this.  I am not sure we would have been able to accomplish this project without his assistance.He is wonderful, developed relationship and stay in touch.  We are also looking at another project and happy to recommend to others." ~ Janeé Wells, Communications Coordinator - Hospitality Center for Chinese

“We keep going back to O’Neill because of their dedication to successful delivery of a project. They are one of the few suppliers who not only do the installations themselves, but they are also dedicated to getting it right and will go above and beyond to make sure the project is perfect.  We know that O’Neill has the same values and standards that we have. That’s why we’ve worked with them for over 8 years and plan on continuing to partner with them again and again.” ~ O'Neill Client
