Client Testimonials

"They are one of the most hard working teams we have had and I just wanted you to know they are worth 10 of the last team we had."

- Anne, Industrial Facility West Allis, WI

" I wanted to recognize our cleaner Iryna; she was cleaning the facility Sunday and found $500 cash on the floor of the conference room!  She texted me photos of the money and where she found it.  We had a contractor in for a meeting Friday afternoon and he apparently dropped it.  Needless to say he was overjoyed and is planning to stop in and personally thank Iryna!


That was a great story to start out the week!  Iryna’s honesty is admirable and we are super excited to have her here!"

- Julie, Office Complex Milwaukee, WI
