"Your team did a great job. You guys rock"
-- Arlene, Office Manager
Dr. Goldenberger, MD., NYU Langone


"The team did a fantastic job. I was at the site Wednesday morning and the difference between where the team had worked and where they hadn't was like night and day. I was really pleased. They were thoughtful, careful, and thorough. A real pleasure to work with."

-Daniel B., Program Director, Creative Company, NYC, 5/19



"I am thrilled with Jose's work. The office is sparkling clean. Thank you for everything."

-Meg N., Senior Client Relations Manager, NYC, 4/19


" I wanted to personally reach out to thank you for taking precautions with the cleaning and floor care for our inspection. It was brought to our attention that once you knew about this inspection, you truly went out of your way to help any way you can. The office looks amazing and the inspector was really pleased when he arrived… the staff, management and myself is also truly happy with the results. We received nothing but raving reviews from the office. This truly helps you stand out from other cleaners for sure. Thank you for all the hard work and we hope to continue doing business with you."

-Anita, C, Facilities Department, Major Medical Company, NYC

"Please forgive my delay in replying. I haven't seen the work your cleaning crew did for myself yet, but I did get a report back from my CEO. He was extremely pleased with their very thorough job. He said that the office is unrecognizable, it's so clean. He is also interested in bringing them back in every six months or so for deep cleaning. Thank you very much for your assistance. As you know, it was really important for us to get that job done."
